Prime Plants for Nature: Backyards for Nature 2014 Native Plant Awards

By Edie Parnum

Each year we select two native plants with exceptional ability to support wildlife. These plants will contribute significantly to the web of life in your yard. They host insects, offer nectar and pollen, and produce fruits, seeds, or nuts. Birds, butterflies, and other insects and animals will feed and prosper.  Most provide shelter and nesting places, too.  Our selections, all native to southeastern Pennsylvania, are easy to grow and readily available at native plant nurseries or native plant sales. Our Prime Plants make attractive additions to your landscape.  We offer awards in two categories: Trees and Shrubs and Perennials.

Our selections for the 2014 Prime Plants for Nature Awards are:

Eastern Red Cedar, Juniperus virginiana                                                     

Wildlife Value: This small evergreen tree is a powerhouse for nature.  Yellow-rumped

Warbler, Eastern Bluebird, and Northern Mockingbird are among the 54 species of birds that eat its long-persisting berry-like cones during the cold months.  Cedar Waxwings areso-named because they’re fond of cedar cones. The foliage hosts the Juniper Hairstreak butterfly, a vulnerable species in Pennsylvania, and several species of moths such as the Curve-lined Angle.  Song Sparrows and other

birds use the dense foliage for nesting places and shelter. Don’t be tempted to buy the similar-looking Leyland Cypress, a non-native that offers little for wildlife.

Growing Conditions: The Eastern Red Cedar tolerates a wide variety of soils and dry to moist growing conditions.  It prefers a sunny spot. These trees are either male or female.  Only the female trees produce fruits, but you’ll also need a male for pollination.

By planting at least three of these trees, you will enhance their wildlife value.    A row of cedars will provide dense shelter for birds. From the human perspective, the cedars can offer privacy. If planted on the north side of your house, they will create a windscreen.

Appearance: This evergreen has a pleasing conical shape.  It grows at a moderate rate (1-2 feet per year) and reaches 15-40 feet at maturity.

Short-toothed Mountain Mint, Pycnanthemum muticum

Wildlife Value: This perennial is a magnet for pollinators.  Butterflies, bees, wasps, and flies are attracted to the copious nectar and pollen this lovely plant produces.  Because it

flowers over a long period of time, it may host thousands of visits by pollinators each season.  With this plant in your yard, you can introduce children to pollination and teach them not to be afraid of bees and wasps.

Growing Conditions: Mountain Mint is a tough plant and will grow well in dry to moist soil in full to part-sun. Like other members of the mint family, it spreads but can easily be controlled, especially early in the growing season. It’s easy to transplant and share with other native plant gardeners.  This perennial is deer-resistant, too.

Appearance:  Mountain Mint grows to about 3-feet tall.  Although the numerous flowers are small and inconspicuous, the foliage is an attractive silvery grey.  The leaves complement other brightly colored flowers in the garden and in flower arrangements, too. This plant’s attractiveness is enhanced by the beautiful butterflies and other pollinating insects that visit.

Milkweeds for Monarchs – 2014

By Barb Elliot

 

“The lowest numbers of Monarchs ever recorded” 

“Monarch migration at risk of disappearing”

This is the devastating news about Monarchs over-wintering in Mexico. These Monarchs migrated last fall from eastern portions of the U.S. and Canada to reach their historic Mexican wintering grounds. Each year scientists count the number of acres of trees where the Monarchs cluster during their winter stay in Mexico. This winter Monarchs covered just 1.7 acres — a significant decline from the previous low of 2.9 acres.

Loss of milkweed is the primary reason for the steep decline in Monarch numbers. Milkweeds are the only plant Monarch caterpillars can eat. Millions of acres of milkweed habitat have disappeared in the mid-west due to the use of genetically modified (GMO) corn and soy crops. Farmers spray their fields with Roundup, and the crops survive. However, this herbicide kills the other plants like milkweed that previously grew in and around crops. Since these Roundup Ready crops came into use over the last 15 years, almost 80% of milkweeds in the mid-west have disappeared. Monarch population decreases have correlated in lock step with the loss of milkweed.  Milkweed habitat is also lost due to development and mowing of roadsides. Extreme weather over the past few years in Mexico, the U.S. and Canada has also contributed to Monarch losses. Cold snaps, heat waves, droughts and heavy rains have also taken a toll on the Monarchs and milkweeds.

As a result, last summer we Monarch-lovers saw few, if any, Monarchs. With these steep declines, we’ll surely see even fewer this summer. However, Monarch experts say that the Monarch population can bounce back – probably not to the high levels of the 1990s, but to a lower “new normal”. To improve their numbers, Monarchs need MORE milkweed.

That’s where we come in. We Monarch-lovers must plant more milkweeds this year. The Monarchs, fewer in numbers now, will need quantities of milkweeds to find the plants easily and lay their eggs. Also, milkweeds are very important plants in the web of life and provide high quality nectar for a variety of other important pollinators.

Pollinators Need Our Help!

By Barb Elliot

The earliest spring flowers will soon emerge.  In my garden I’ll admire the delicate white petals of Bloodroot, the first to bloom. Soon I’ll enjoy the blue bell-like flowers of Jacob’s Ladder, the bright yellow of Golden Ragwort, and striking red blooms of Wild Columbine.   The flowers are charming, but I will be more captivated by their insect visitors.  Small bees and flies will fly from blossom to blossom. Working intently, they will stop briefly to feed and gather nectar and pollen.  These will be the first pollinators of the year.

As spring and summer progress, pollinators will visit the succession of blooms on my native trees, shrubs, and perennials.  Bees, butterflies, flies, beetles, and wasps will be at work.  I’ll watch each butterfly unfurl its straw-like proboscis to daintily probe flower heads and sip nectar.  Yellow pollen grains will dot the heads and bodies of bees and flies.  Female bees will sport saddlebag-like pollen baskets on their hind legs.  The undersides of leafcutter bees’ abdomens will be golden from pollen grains stored on special hairs.

I’ll notice the size, shape, and tongue lengths of pollinators – characteristics that enable some to better exploit different shaped flowers than others.  Iridescent green sweat bees will glisten in the sunlight as they feed on nectar.  The strikingly-marked Locust Borer Beetle will catch my attention as it methodically forages for pollen on my goldenrods.  I’ll marvel at how close I can get to colorful wasps as they busily collect nectar.  Hover flies will hang suspended in air as they take a break from feeding on nectar and pollen.  After dark, with my flashlight, I’ll find moths flying from flower to flower, performing nighttime pollination.

My flowering plants put on their royal finery to entice these pollinators, not me.  Their showy colors and patterns advertise and guide the pollinators to the plants’ nectar and pollen.  The plants must rely on the pollinators to transport pollen among different flowers of the same species.  This cross-pollination enables plants to produce the seeds and fruit needed  for reproduction.  Well-pollinated plants bear more fruit, produce genetically diverse seed, and are healthier. For the pollinators the nectar provides carbohydrates for energy. The pollen supplies them and their offspring with protein, vitamins, minerals, fats, and starches.

Pollinators play essential roles in our ecosystems.  Seventy-five percent of the world’s plants require pollinators to produce seed or fruit.  One-third of our food supply comes from pollinator-reliant plants. Birds and other wildlife in my yard and the world over eat

the seeds and fruits produced by pollinator-dependent plants.  Pollinators themselves are food for birds and other animals, including insects.  A diverse population of pollinators is critical to the web of life.

Unfortunately, many pollinators are in decline.  Some are threatened with extinction.  Our most beloved pollinator, the Monarch butterfly, is in serious trouble.  The eastern U.S. population crashed in 2013, and the smallest number on record over-wintered in Mexico this year.  Not only Monarchs but other pollinator populations, including bees, our most prolific pollinators, are in trouble, too. The effects of Colony Collapse Disorder on non-native honeybee populations are well known. However, many of our 4,000 U.S. native bee species, key pollinators of both

native plants and crops, are also at risk.  Bumble bees seem particularly hard hit, with about half of our 47 U.S. species in decline.  Some are in danger of extinction. Less studied pollinators like beetles, wasps, and moths are likely declining as well.

Loss of good foraging and nesting habitat is the primary cause for pollinator declines.  Pesticides and introduced parasites add to the toll.  Many experts believe neonicotinoid insecticides pose a particular threat to bees and other pollinators.  Those that forage on treated plants become weak or die.  “Neonics” and other systemic pesticides are taken up through a plant’s roots and travel to all parts of the plant, including its nectar and pollen.  Last June, 50,000 bumble bees foraging on flowering trees at a single location in Oregon were killed after the trees were sprayed with a neonicotenoid.  Neonics are present in a variety of insecticide brands commonly sold to gardeners. They are also used in nurseries that raise plants.  In fact, some plants sold as bee-attractants contain neonicotenoids.

Despite all the threats, we gardeners can help sustain pollinator populations in our area.  (See table below.)  Some gardeners like to attract butterflies, but balk at inviting moths, bees, beetles, flies, and wasps.  However, these insects have important roles to play in the web of life and are generally harmless to gardeners.  Native bees are unaggressive and rarely sting. Even wasps are docile when foraging on flowers, although they may forcefully defend a nest.  By incorporating a variety of native plants in our yards, our most important conservation action, we will attract pollinators that are also predators and keep insect populations in check.  Various beetles, flies, and wasps prey on aphids and other insect pests.  By growing a diversity of native plants (see plant list below), we will encourage a healthy balance of insects in our gardens.

I hope the plight of the Monarch butterfly will compel us to action. We must help not just the Monarchs* but the less charismatic butterfly, bee, fly, wasp, beetle, and moth pollinators as well.  For too long, we have ignored pollinators or treated them as pests to be destroyed.  We have gardened for aesthetics and our enjoyment without considering nature.  These beneficial creatures are crucial players in the web of life in our own gardens and beyond. We can make a difference for them.  We and our gardens will benefit.

 *Please note that we will be selling milkweed plants for Monarchs again this year!  Stay tuned for an upcoming post about Monarchs and details of the milkweed sale.

How to Help Pollinators
Provide Food 
  • Plant:
¨  A variety of nectar- and pollen-rich native plants. Strive for 8 or more species.
¨   Perennials in clusters, preferably 5 or more of a single species, so plants are easily found.
¨   For a succession of blooms from early spring through late fall.
¨   Natives with different flower shapes for pollinators or varied sizes, shapes, and tongue lengths.
¨   Host plants for butterflies and moths.
  • Buy plants at local native plant retailers or where sellers identify whether plants are pre-treated with systemic pesticides such as neonicotinoids.
  • Remove invasive plants so they crowd out natives
Provide nesting and overwintering sites
  • Leave:
¨  Areas of bare soil in sunny, well-drained spots.
¨   Stumps, logs on the ground, dead branches and trees.
¨   Leaf litter for over-wintering butterflies, moths, beetles and their larvae or pupae
¨   Stems of perennials standing from fall through late winter
Provide water
  • Add a shallow dish with sloped sides for easy entry and exit
  • Keep an area of soil moist or muddy for butterflies and other pollinators that forage for minerals and salts in soil
Prevent pesticide poisoning
  • Don’t use pesticides, but especially avoid neonicotinoids.  Click here for a list of common brands containing neonics.
  • Don’t apply herbicides or fungicides to lawn or beds with nest sites or pollinator plants
Other Ways to Help Pollinators
  • Make a commitment to protect pollinators by getting your yard certified as a pollinator habitat and posting a sign.  See The Xerces Society’s “Bring Back the Pollinators” campaign
  • Become a citizen scientist to help scientists track pollinator populations, such as by reporting sightings of bumble bees to Bumble Bee Watch or other species to Project NoahXerces Bring Back the Pollinators habitatsignfull (1)

Resolutions to Bring Nature to Your Yard in 2014

By Edie Parnum

Oh, no, you say.  I never make resolutions—too much self-denial and discipline.

Here are some resolutions that don’t require much work.  And, in fact, they’ll add pleasure to your life. Pick one of these to get started. Birds, butterflies, and other creatures will visit your yard.  Pick three, and you’ll see nature flourish abundantly–guaranteed.

  1. Plant a tree.  Adding a native (historically part of our local ecosystem and food web) tree is the single best contribution you can make to your property’s habitat.  It will offer more food, shelter, and nesting places than any other plant.  Besides providing seeds, fruits, or nuts directly to birds and other animals, the tree’s leaves host native insects.  Birds and other small animals eat native insects in

    large quantities. The small animals are prey to larger ones.  Thus, this native tree and its insects contribute enormously to fuel your yard’s ecosystem.  It’s easy and inexpensive to plant a sapling tree.  It will establish quickly, grow fast, and sustain wildlife for decades.  Surely you have room for one tree (small or large), perhaps several of them.  Native oaks offer the best wildlife value but check our website for other valuable native trees.

  2. Plant shrubs.  Requiring less space than a tree, they offer nearly as much value to a healthy habitat. Besides the nutritious fruits these woody plants produce, insects eat their leaves.  As with trees, these insects sustain birds and the other animals in the web of life.  Also, dense deciduous and evergreen shrubs provide

    cover and places for nesting birds.  Highbush Blueberry (Vaccinium corymbosum), Red and Black Chokeberry (Aronia sp.), Northern Bayberry (Morella pensylvanica), and various native dogwoods (Cornus sp.) and viburnums (Viburnum sp.) are excellent choices. Plant three or more of each species.  See our website for recommended shrubs.

  3. Plant perennials, not annuals.  Annual flowers are so much trouble to put in each year, fertilize, and keep watered.  Forget the bothersome begonias, impatiens, marigolds, coleus. petunias, and the like.  Native perennials will grow

    and bloom beautifully for years without any extra care. My favorites are Butterfly Weed (Asclepias tuberosa), Summer Phlox (Phlox paniculata), New England Aster (Symphyotrichum novae-angelae), Bee Balm (Monarda didyma), and Mountain Mint (Pycnanthemum muticum), but there are many other beautiful native perennials. All provide nectar and pollen for bees, butterflies, and other pollinators. Like other native plants, they host native insects, too.

  4. Plant a vine.  If you want hummingbirds in your yard, plant a Trumpet Honeysuckle (Lonicera sempervirens) (not the invasive Japanese Honeysuckle, of course) or Trumpet Vine (Campsis radicans).  Virgin’s Bower (Clematis virginiana) is a magnet for bees, moths, and other pollinators.
  5. Plant groundcovers.  Minimize weeding.  Instead, cover the ground with native groundcovers like Allegheny Pachysandra (Pachysandra procumbens), Green and Gold (Chrysogonum virginianum), and Golden Ragwort (Packera aurea).
  6. Take out a patch of lawn.   It’s the most biologically deficient part of your yard—not much better than your driveway.  Every year decrease the size of your lawn
    Great-spangled Fritillary nectaring on False Sunflower.  Click to enlarge.

    Great-spangled Fritillary nectaring on False Sunflower.

    and keep only what you use for family activities, dog play, and other outdoor activities.  Instead of turf grass, plant any and all of the above: trees, shrubs, perennials, vines, groundcovers.

  7. Take out invasives.  Invasive plants spread aggressively and crowd out desirable native vegetation.  Yes, whether you cut, pull, or smother the invasives, it can be a lot of work.  Plus, if you leave the ground bare afterward, of course they’ll come back.  Immediately fill in the cleared area with native plants.
  8. Learn native plants.  You can attend botany walks at Bowman’s Hill Wildflower Preserve, Heinz National Wildlife Refuge, and Tyler Arboretum.  Visit a botanical preserve where native plants are labeled such as Bowman’s Hill and Jenkins Arboretum. When buying plants at native plant nurseries like Redbud Nursery and Yellow Springs Farm, you’ll see labelled plants and learn growing tips from their knowledgeable staffs.  Use the internet photos and gardening information, too.
  9. Read a book.  I recommend Bringing Nature Home: How You Can Sustain Wildlife with Native Plants.  The author, Douglas Tallamy, professor and chair of the Department of Entomology and Wildlife Ecology at the University of Delaware, will inspire you to plant native plants and increase your determination to host native insects, birds, and butterflies in your yard.

  10. Walk around and enjoy nature in your yard frequently.  Take your binoculars to better see and learn about the birds, butterflies, and other creatures that live in your garden.  With a camera you can take photos of your plants and wildlife sightings.   You’ll be inspired to become more familiar with your own wildlife preserve. Spread your enthusiasm: take a child with you on your backyard adventures.

Personally I will do all ten of these—with pleasure.

If you’re a beginner to habitat gardening, pick one of these ideas to get started.  Perhaps you can tackle two or three this year, but don’t get overly ambitious.  Start planning now in the dead of winter. Time and money may be limited, but you can start small and keep improving your habitat each year.  Before long you’ll notice more insects including butterflies and moths, more birds, and, indeed, much more wildlife activity in your yard.

Do something for nature in 2014.

 

Brown Gold: The Gift of Fall Leaves

By Barb Elliot

The brilliant yellow, orange, and red leaves are turning brown.  The beauty of autumn is fleeting and soon all the leaves will be on the ground.  This “leaf litter” is not trash.  The leaves nourish my garden.  They’re home to tiny creatures that are essential to my garden’s ecosystem.  These leaves are the gift of fall.

Last year, instead of buying expensive mulch, I mulched with fallen leaves.  My trees and shrubs produce leaves abundantly and without charge.  Wherever possible, I left them to decompose where they fell.  I raked the rest from my lawn into my planting beds.   Also, I collected leaves from my neighbors and added them to my garden.  The leaves choked out the weeds, retained moisture, reduced erosion, and insulated the roots of my plants against winter cold.  A natural fertilizer, they added nutrients to my soil.  My plants grew remarkably well this year.

Leaf litter (or duff) offers exceptional benefits.  Myriad creatures live in the duff and play key roles in the healthy, diverse ecosystem of my yard.  Countless microorganisms and tiny invertebrates break down the leaves into basic elements that enrich the soil.  Bacteria and fungi accomplish the bulk of decomposition.  Invertebrates such as snails, slugs, and earthworms assist in the process and contribute to the web of life in the leaves and soil.

Many, many arthropods — creatures with exoskeletons and jointed legs — such as sowbugs, spiders, daddy longlegs, millipedes, centipedes, protruans, and double-tails play an important role, too.  Spring-tails and mites, the most numerous, are so small they are rarely observed by gardeners.  Many beneficial insects such as crickets, beetles, flies, bees, wasps, and ants also live in the duff.  All of these creatures are food for other invertebrates or larger animals such as salamanders, toads, and mice.  These in turn are eaten by birds, snakes, or larger mammals.  The large and small animals associated with the leaf layer form a natural predator-prey balance in the ecosystem.

We butterfly-lovers (and fellow moth-lovers, too) know the leaf layer shelters these winged beauties in their various life stages.  Numerous butterfly and moth species

overwinter in the leaf litter as eggs, larvae (caterpillars), pupae (chrysalides or cocoons) or adults.  For instance, the lovely Red-banded Hairstreak, which has visited my yard, lays its eggs on the underside of fallen sumac or oak leaves. When the eggs hatch, the caterpillars eat the leaves and then overwinter in the leaf layer as late-stage caterpillars or chrysalides.  Tawny Emperor butterfly caterpillars wrap themselves in a curled leaf and overwinter as caterpillars.

Fuzzy Woolly Bear caterpillars are now searching for good spots under the leaf layer where they will hibernate for the winter.  In spring, each will spin a cocoon and emerge as an Isabella Tiger Moth.

The Luna Moth, one of our largest and most beautiful moths, overwinters as a cocoon in the dead leaves.  Unfortunately, when we treat our leaves as trash, we are also throwing out the butterflies and moths that will grace our yards next spring and summer.

Leaf litter benefits birds, too.  In my yard I see ground-feeding Eastern Towhees, Gray Catbirds, Northern Flickers, and sparrows picking through the leaves.  They find insects and other invertebrates to feed themselves and their protein-hungry nestlings. One spring, a migrating Brown Thrasher, a species I don’t see very often, foraged in the

leaves of my flower bed.   Birds that nest in my yard search the leaf layer for nesting materials such as leaf stems, twigs, and moss.

In our society, we are expected to be yard “neatniks”.  We conscientiously rake or blow leaves into piles and then stuff them into bags.  Picked up at the curb, the leaves end up in a landfill or a huge “leaf compost” pile that smothers beneficial creatures.  Personally, I choose to keep all my own leaves and add those discarded by neighbors so they can decompose naturally in my yard.  Maybe you, too, will rescue leaves from neighbors.  If you want to start small, rake some leaves into a back corner of your yard.  Although shredding leaves speeds up decomposition, I refrain for fear I’ll destroy the insects and other animals living there.

I’m making a vow.  I will never again throw out next year’s butterflies and moths or the other animals that live in my leaf litter.  Dead leaves are a gift to biodiversity and the web of life.  Leaf mulch is brown gold.  I’m joining the new movement* to make fallen leaves socially acceptable as garden mulch.   I’m in!  Are you?

Native Berries for Fall Migrants

By Edie Parnum

Birds were dropping out of the sky into the trees and shrubs around me. It was daybreak on a fall morning in my backyard.  Though I could see only silhouettes, I recognized the chips of robins and Swainson’s Thrushes.  In the dim light I couldn’t identify the other numerous birds but knew these were migrants that had flown non-stop from the north during the night.

After their nighttime exertion, they were exhausted and ravenously hungry. They needed to find high-energy food and to revive in a habitat offering shelter from predators.  With most of the surrounding area covered with buildings, roads, parking

lots, and sterile lawns, they were desperate for sustenance.  From above, the migrants probably see the local parks as deceptively inviting, but the grass and other non-native vegetation provide little nutritious food.  Their energy depleted, these migrants need familiar and nourishing native plant food.  Otherwise they are in trouble.

Watching these migrants, I imagine myself on a road trip, one I’ve done many times.  After hours of driving, I’m hungry, tired, and low on gas.  I’m looking forward to Rosie’s Restaurant, a favorite stop for good food, gas, and a respite from the journey.  To my dismay, the restaurant and adjacent gas station are gone.  Wasting time and energy, I must drive around randomly to locate what I need before resuming my trip.

Migrants often find my yard and use it to rest and refuel.  During fall migration, especially after a cold front, I search for recent arrivals.  Sometimes I find thrushes, tanagers, grosbeaks, and warblers eating berries on the Virginia Creeper, Arrowwood Viburnum, Winterberry Holly, Spicebush, Black Chokeberry, Flowering Dogwood, Crabapple, and Northern Bayberry I’ve planted for them. One winter a southbound Hermit Thrush stayed in my yard all winter eating American Holly berries.

This fall I’ve been watching a Gray Catbird eating berries on the Virginia Creeper

hanging above my deck railing.  Because the bird is just a few feet away, I don’t really need my binoculars.  It lands on a branch, leans forward, grabs one of the blue-black berries, then quickly swallows—again and again, all day long.  Either a resident breeder soon to migrate or a recent arrival using my yard as a stopover, this bird needs these berries. Besides Gray Catbird I’ve seen Red-bellied Woodpecker, Northern Flicker, Brown Thrasher, Cedar Waxwing, Eastern Bluebird, Swainson’s Thrush, American Robin, Cape May Warbler, and Yellow-rumped Warbler eating Virginia Creeper berries.

Prior to migration, songbirds must increase their weight by 50-100%.  Thrushes, grosbeaks, waxwings, orioles, tanagers, and other songbirds switch from a diet of insects to mostly berries.  Finding berries consumes less energy than pursuing insects.  Scott McWilliams and Navindra Seeram, researchers at the University of Rhode Island, are studying the diet of birds preparing for migration on Block Island.  According to this new research, birds select deeply-pigmented berries

that are high in antioxidants and fat prior to migration.  Antioxidants help birds(as well as humans) handle stress.  Because migration is certainly stressful, birds need to find nutrient-rich berries at stopovers along their migratory routes.

Migration is hazardous for birds.  On their southward journey they fly at night for four to six hours without a break. They must stop and refuel several times before reaching their wintering grounds, especially if their final destination is the tropics.  They spend four to five days at each stopover where most consume nutrient-rich berries.  If they fail to find sufficient fuel for the next leg of their journey, they become weak and vulnerable to hawks, owls, and other predators.

Scientists tell us even small patches of native plants can provide food and shelter for migrating birds.  On my three quarter acre property, I’ve planted scores of fruit-bearing native shrubs, trees, and vines.  Besides the shrubs mentioned, I’ve recently planted Black Gum, Hackberry, Sassafras, and Spicebush that will offer fruits in future autumns.  Also, in a few spots I allow Pokeweed (regrettably considered a weed by most gardeners) to grow and produce beautiful dark purple berries irresistible to birds.

Since many ornamental and invasive non-native plants produce berries, why are native plants so important for migrating birds?  With their high fat content and extra antioxidants, native berries are highly nutritious.  Because the natives usually have

strongly-colored berries, either black or red, or have leaves or stems that are bright red, birds can easily find them.  Also, the native berries ripen at the right time.  Many migrants, especially warblers, continue to eat insects as well—found primarily on native plants.  If necessary, of course, birds will also eat the less nutritious fruits of non-native plants.

Most yards have room for shrubs.  You can plant native fruit-bearing shrubs and small trees around your property’s perimeter to create a hedgerow laden with nutritious fall fruits.  You can also group them around isolated trees.  By reducing your lawn, you’ll find room for more shrubs and other fruiting plants.

Birds, especially those that migrate to the tropics, are in trouble.  On average, the populations of long-distance migrant species drop 1% each year. We assume we can do little except give money to organizations that preserve land.  However, we can help migrating birds survive their perilous and crucial journeys by growing the plants they need and love.

Moth Night

By Edie Parnum

Moths are underappreciated.  Most people think they’re dull and uninteresting.  They ignore those nameless little moths that fly up while walking through the grass.  Those moth pests in the kitchen cupboards are considered just that—pests. True, most of us

can be captivated by a large, daytime moth like a Hummingbird Clearwing Moth sipping nectar from flowers.  However, because moths are usually nighttime creatures, most folks have little appreciation of their variety, esthetic appeal, and role in the web of life.  As for myself, I confess to moth love.

Moth Night is now an annual event in my backyard. A few weeks ago, I invited nature-loving family members and friends for nighttime “mothing”.  A few hours before sunset, I prepared for the occasion.  Since a great many nocturnal moths are attracted to light, I hung two white cotton sheets and positioned lights in front of them.  One light is a grow light and the other is a black light.  Both of these attract moths because they project a wider range of UV light than standard incandescent or florescent light bulbs. Some moths do not come to lights.  Instead, I lured them to a fermented concoction (see recipe below) I painted on tree trunks.

Once it was quite dark, we ventured out into the darkness. Using our flashlights or headlamps, we observed the moths attracted to the lighted sheets and tree trunks.  By shining our lights back and forth in the garden, we found more moths hidden in the vegetation, especially on flowers. Sometimes their eyes reflected back to us.  Big and small, ornate and plain, colorful and monochromatic—they were there.

We often heard someone say, “Look at this one!”  That’s what my friend Mike said when he found the Sad Underwing (Catocala maestosa).  We were happy to see this intricately patterned two-inch species.  I presume it’s called “sad” because the underwing

(hindwing) is plain.  Another time Barb, my friend and colleague, discovered The Sweetheart (Catocala amatrix), an Underwing that charmed us with its rosy-pink hindwing pattern. The uncommon Hop’s Anglewing (Nyphonix segregata) was a good find that night.

We “moth-ers” exclaim “ooh” and “ah” frequently because moths are varied and beautiful creatures.   They display a variety of colors including pink, purple, orange, green, and yellow.  Some shimmer in the light or have iridescent spots. Those that are orange and black are toxic or pretending to be. True, many of them are just shades of tan and grey, but often the patterns are well-defined and elaborate. Others are camouflaged to look like dead leaves or bird droppings.

The shapes can be interesting, too. We see wings that are deeply scalloped, creased, or curled.  The Plume Moths with their skinny wings look like miniature airplanes. Moth antennae sometimes resemble feathers.  Bizarre hairy tufts can show up almost anywhere on their bodies: the legs, thorax, or abdomen.

By looking for the eye-shine of other creatures, we discovered bees, caterpillars, praying mantises, spiders, and cicadas.  My nine-year-old grandson found and identified a Leopard Slug (a creature from the netherworld?) eating the bait on a tree trunk.  We listened for night sounds, too, and heard the whinny of a screech owl and squeaks of flying squirrels.

Many of us took photos and then later admired the details on our computer screens.  That’s when I try my hand at moth ID.  It’s difficult.  After all, 11, 000 species of moths in North America have been identified.  Moths outnumber butterfly species 11 to one.

After I’ve identified a moth, I note its host plants.  These are the plants where the moth lived its earlier stages as an egg and caterpillar and where the female adult moth will lay eggs for the next generation.  Many of these host plants grow on my property (see below). Although I live in a congested suburban area, my ¾-acre property has a good variety of the native perennials, grasses, and woody plants that moths use. And, I don’t use pesticides. It is moth-friendly habitat.

Why should we care about moths?  Moths are important links in the web of life.  The adult moths are good pollinators and are food for birds and bats.  Birds, especially nestling birds, also feed on moths in their egg, larvae, or caterpillar stages.   Small mammals, reptiles, and other insect predators consume moths in their various stages as well. In fact, insects power our ecosystem and are the most important animals of all.

Moths have lured me into the nighttime natural world of my backyard.  Now I feel more intimately connected to the lives of moths and other creatures that contribute to my property’s biodiversity.  I won’t wait until next year to hold another Moth Night.  I’ve caught the moth bug.

Edie’s Bait Recipe

  • One or two overripe bananas, mashed
  • Dollop of molasses
  • Small scoop of brown sugar
  • Glug or two of beer (stale is ok)
  1. No need to be precise.  Mix together and adjust proportions to create a pancake batter consistency.
  2. Leave it for a day or two in a warm place.  I like to take it outside for a few hours to let bees and flies add their contributions.
  3. With a paint brush, smear this concoction at eye level on tree trunks about an hour or two before sunset.

Lightning Bugs: Nighttime Marvels

By Barb Elliot

Magical creatures on the wing in my backyard fairyland – that’s what I thought as a little kid.  Even the fireflies I caught and put into a jar flashed miraculously.  “How do they make that light?” I wondered.  Children universally love to watch these fascinating insects.  In fact, it was kids from Upper Darby, Pennsylvania who successfully

campaigned to have the lightning bug named Pennsylvania’s state insect in 1974.  No longer a child myself, nevertheless, my backyard seems an enchanted place on summer evenings, with spots of light flashing from the ground to the treetops.

Lightning bugs, or fireflies, are actually neither true bugs nor flies, but beetles.  There are 2,000 different species worldwide, with 175 in North America and about 35 species in Pennsylvania.   The adults live for just two to four weeks, and must attract mates and

reproduce during that time.  Scientists believe they eat pollen or nectar, though some may eat other small insects, or nothing at all.  Their flashes are courtship communications that enable the fireflies to find mates of their own species.  They are also a warning to potential predators like birds and spiders that firefly bodies contain toxic chemicals.

Each species has a characteristic flash pattern, with a different color, duration and/or rhythm.    Females generally don’t fly, but wait in grasses, shrubs, or trees to watch for the flash sequences of males of their own species.   When she spots a male of her species whose flashes she likes, the female flashes in response, inviting the male to come to her and mate.  In late summer, females lay eggs on the soil, leaf

litter or woody debris. Eggs
hatch in a few weeks and the larvae, sometimes called “glow worms”, live in leaf litter.   These voracious predators eat other insects, mites, aphids, earthworms,  slugs and snails.  Thus, they are quite useful in helping to control pests in the garden.  They can even track down a slug or snail by detecting and following its  slime trail. After injecting poison that immobilizes its quarry and liquefies internal  organs, the firefly larva sucks out

and easily digests the victim.   In late fall, the larvae burrow under the bark of woody stems or into the soil, where they overwinter.   Re-emerging in spring,  they again feed on invertebrates for a few weeks.  They then re-enter the soil, pupate, and in  early to mid-summer emerge as adult  fireflies.

Intrigue and cunning among lightning bugs makes their world a dangerous place.   Just as the sirens of Greek mythology lured sailors to their deaths, females of the genus Photuris mimic the flash of Photinus females in order to seduce Photinus males.  When they trick a Photinus male into coming to them, the Photuris female eats the male.  She gains energy to produce better and more eggs and incorporates the male Photinus’s protective toxins.

Some species have the capacity to produce light in all stages of their lifecycle – as eggs, larvae, pupae, and adults.  The light is created by an enzyme in the firefly’s tail that initiates a chemical
process called the luciferin-luciferase reaction.  Their light production is almost 100%
efficient, with almost no heat lost as a by-product.   Researchers have been able to isolate the
genes used for firefly’s light and use them to track, mark, and assist in the killing of human cancer cells.  In fact, biochemical companies have commercially harvested lightning bugs for their luciferin and luciferase.

Firefly populations are declining in the U.S. and in many parts of the world.    Scientists are researching reasons for the decline of some populations.  Certainly, a major threat is loss of habitat through development.  Fireflies tend to show site fidelity — with generation after generation finding mates, laying eggs, and emerging in the same location every year.  When such sites are lost, we lose that group of fireflies forever.

Here are some actions we can take to ensure that we don’t lose the lightning bugs where we live:

  • Eliminate the use of pesticides, including those intended to kill grubs in lawns.
  • Don’t turn on outdoor lights at night.   To mate and reproduce successfully, fireflies must be able to see the flashing of other fireflies.  If you must use outdoor lighting, use motion-detector lights.
  • To create habitat for firefly larvae, place some logs on the ground and use leaf litter (chopped if you prefer) to mulch flower beds, trees, and shrubs.
  • Since most firefly species thrive around water, add a pond to your landscape. Alternatively, you can create a depression that stays moist or keep an area of your yard well-watered.   (To kill mosquito larvae and not harm other wildlife, add Mosquito Dunks® to a pond/standing water.)
  • Plant trees.  Native trees, especially evergreens such as White Pine (Pinus strobus) provide areas of low light and shade that give fireflies more time to find mates.
  • Consider mowing your grass less frequently.  Lightning bugs spend daylight hours on the ground and frequent mowing is likely harmful.  Create a perennial bed or pocket meadow of densely planted native grasses and perennials.  This will allow fireflies to hide during the day, while providing high vantage points for flashing at night.

  • If your kids or grandkids catch fireflies, encourage them to handle them gently and release them after a few hours.  They’ll be glad their fireflies can thrive and produce another generation.
  • Last, since relatively little is known about this enchanting insect, consider taking part in the Firefly Watch citizen science project. Participation takes just 10 minutes of observation in your yard per week over the summer, and you’ll be joining citizen scientists in Canada and 40 U.S. states who are contributing data about their lightning bug sightings.

Let’s work together to keep our southeastern Pennsylvania lightning bug population healthy by providing the habitat they need in our neighborhoods.  If we do, we will continue to enjoy the free light show each summer. Generations of kids to come will enjoy their magic.

Keeping a Yard Bird List

By Edie Parnum

Looking out my kitchen window as I habitually do, I spotted a large dark bird showing bold white flashes on its wings flying to a snag at the back of my property.   Luckily, I keep my binoculars within reach on the counter.  It was a Pileated Woodpecker, a first for my yard.

This Pileated Woodpecker was #105 on my Yard Bird List.  Every new bird added to the list is special to me.  My count makes me proud that I’ve planted bird-friendly natives that host a variety of birds.  However, because my young trees are too immature to attract this woodpecker, the pileated was a surprise. It visited my yard because I left the trunk and some major branches on a dead tree rather than cut it to the ground.

Keeping the yard list helps me hone my ID skills, visual and auditory.  A Least Flycatcher, one of those challenging
Empidonax flycatchers, once lingered in my yard for two days.  Seated on my deck, I could leisurely, but closely observe its diagnostic bold eye-ring, big head, short wings, and narrow tail. It did not sing, but occasionally gave a call, a little “pit” sound.  If I had been elsewhere on a bird walk, I
would have made a quick ID and quickly moved on to look for other birds.

Closely watching the birds in my ¾-acre yard improves my knowledge of their habits, food preferences, seasonality, and habitat requirements. I note the species of birds using each plant and the time of year.  In the spring, warblers, vireos, orioles, and other migrants glean caterpillars from the foliage of my Black Cherry and the young oaks and birches. In the fall, waxwings, mockingbirds, woodpeckers, robins, and other thrushes devour the crabapples.  A variety of sparrows eat seeds in my 1/10-acre meadow in the autumn.  Yellow-bellied Sapsuckers bore holes in the Sweet Gum and crabapples in the spring and fall. A Magnolia Warbler foraged in the Northern Bayberry last September, but I’m not sure whether it was eating the berries or bugs. I’ll take a closer look if it returns to the same shrubs next fall.

Do I count birds that fly over my yard without landing, you might ask?  Yes, although I can’t claim my improved habitat offers any sustenance to the flyovers.  Furthermore, I even added a distant, heard-only, Fish Crow to my list.   Perhaps I’m inflating my yard count, but I’m staying observant of all the birdlife around me. On the other hand, I didn’t count a Red-shouldered Hawk perched three blocks away that never flew over my property.

I keep a list of missing birds, too. I haven’t seen a Willow Flycatcher, Veery, or a White-eyed Vireo —how could that be?!   Lacking a stream or wetland on my property, I may never see a Louisiana and Northern Waterthrush.  Mature native trees are still scarce here, so the warbler list is slim–just 20 species.  Maybe during this fall migration or next spring I’ll find the missing Orange-crowned, Tennessee, Cerulean, Bay-breasted, Connecticut, Mourning, Wilson’s, or Hooded Warbler.  I probably won’t ever get an outlier like American Woodcock (wrong habitat), but I have hopes that a Northern Saw-Whet Owl will use my Eastern Red Cedar one day.

Keeping a yard list can be as simple as noting the birds on a piece of paper.  Or, even better, you can use eBird, a listing program that is one of the Cornell University Laboratory of Ornithology’s citizen science projects.  By entering your yard bird sightings into eBird, you’ll have access to the records of other local as well as far-flung birders.  Your data will be incorporated into Cornell’s records and be used to track bird populations by educators, conservationists, and ornithologists around the world.  http://ebird.org/content/ebird/ or http://ebird.org/content/pa/

Watching for birds is a part of my everyday life.  I can observe my feeder birds while working at my kitchen sink.  As I move around the house, I always glance out the closest window.  While relaxing on my deck, I’ve spotted many new yard birds.  I regularly take walks around the yard, too.  On good migration days, I go out early to look for new arrivals.  No travel is necessary, and there’s still time for the rest of the day’s activities.  Every day I’m connected to nature.

An Update: Milkweeds for Monarchs Initiative

By Barb Elliot

In my March 23rd post, Monarchs: A Call to Action (see below) Edie and I offered milkweed plants for sale.  As I said then, the Monarch butterfly population is in sharp decline due to loss of habitat . We were inspired to join Monarch Watch’s (www.monarchwatch.org) national call to action.  To save this species we must plant more milkweeds, the Monarch caterpillars’ only food.

The response to our offer was fantastic!  We received one hundred thirty-five orders for a total of 2,400 plants.  There is a waiting list of people who missed the April 1st order deadline and want to buy any leftover plants.

Orders came from Monarch enthusiasts across the southeastern Pennsylvania area –
Philadelphia, Bucks, Montgomery, Chester, and Delaware counties -and even from  south New Jersey and central Pennsylvania. We were impressed by the networking and sharing about the milkweeds that took place via word of mouth and social media, including Facebook and list-servs.  Inquiries about buying milkweed came from as far away as Minnesota and Virginia.

When the milkweed plants become available in early June, they will be planted in a variety of settings, including the backyards of many private homes, an in-home day care center in the Mt. Airy section of Philadelphia, a community vegetable garden on the Main Line, a condominium community, an elementary school yard and organic garden, a middle school yard, and a churchyard in Malvern.  A retired couple in Downingtown inspired adults and children in their neighborhood to order 150 milkweeds.

Thanks to all of you who ordered plants and/or shared the need and opportunity with family, friends, and neighbors!  We fervently hope that similar efforts are taking place across the country to help save the Monarchs.
