Can a Caterpillar Be Charismatic?

By Edie Parnum

Yes, of course. I was thrilled to discover a brown-hooded owlet in my late October garden. This caterpillar with its glossy yellow, red, blue, and black pattern is beautiful. It is pre-frost as I write, so the leaves of the aster where it’s feeding are still green and evidently tasty.

For three days I’ve watched it feeding and pooping. Thankfully, the nearby hungry birds have not spotted it. Frost is coming, so I hope it will soon crawl down the aster plant where it has been feeding and make its pupa. As a caterpillar this insect won’t live through the winter, but its pupa can survive unseen in the soil or decaying leaf litter. In the spring after undergoing metamorphosis, a drab brown one-inch adult moth will

emerge. This night-flying moth will visit flowers for their nectar and spread the pollen to fertilize other plants. Then it will mate and lay eggs on asters and goldenrods that will hatch into these caterpillars. To complete its entire life cycle, my caterpillar needs humus-rich soil, native asters and goldenrods, and nectar-rich perennial flowers.

The brown-hooded owlet is my favorite caterpillar. I wish more people had favorite caterpillars. They are essential bird food and as adults become excellent pollinators. In the case of the brown-hooded owlet caterpillars, they require native asters and goldenrods as their host plants.

We need beautiful caterpillars and drab ones, too. Without them birds will suffer, plants (including our food plants) will be less plentiful, and our lives less rich. Let’s plant more host plants and leave decaying leaf litter for the caterpillars.

A Caterpillar-Raising Extravaganza!

By Barb Elliot, Ph.D.

In July 2017, I came home from Mothapalooza, a conference for moth enthusiasts, with a Cecropia moth (Hyalophora cecropia) caterpillar.  I was excited.  The beautiful adult Cecropia (Hyalophora cecropia) is the largest moth in North America with a wingspan from 5″ – 7″. The showy caterpillars are chunky and grow to 4”- 4.5”. Although I had raised butterfly and moth caterpillars previously to increase their chances of survival, I now had the opportunity to observe the life cycle of this iconic silk moth and learn about its role in our ecosystem.

My caterpillar was almost full grown, but still had a voracious appetite. I kept it in a butterfly cage, provided a constant supply of fresh River Birch leaves, and removed the caterpillar waste (frass) each day.  Cecropia caterpillars can eat other native tree and shrub leaves including elm, oak, maple, apple, cherry, ash, sassafras and willow, but prefer to stick to one kind once they begin eating. A Cecropia caterpillar gains more

than a thousand times its weight between hatching from its egg to being fully grown and ready to pupate and spin its cocoon.

In late summer, my caterpillar clung to a twig in the cage and spun a cocoon around itself.  Inside the protective silk, it changed from a caterpillar to a dark brown pupa, the third stage in its development.

Many months later, on June 21, 2018, with metamorphosis complete, a spectacular female Cecropia moth emerged (eclosed) from the cocoon. With only a week to live and with no mouth parts to eat and drink, this adult female’s sole job was to mate and lay eggs.

I decided to keep the moth outside overnight to see if she could attract a mate.  At dusk, I put her in a wire cage with holes sufficiently large for mating to occur.  A male, with its large, feathery antennae, can detect the pheromones a female emits and hone in from over a mile away.

I got up at 5 AM the next morning to check on her.  A male was clinging to the cage and mating with her!  The two mated all day and de-coupled just before dark.  Right away she began laying eggs.  I released the male so he could mate with other females.

During the overnight hours, she laid about 130 eggs.  After she rested, I released her so she could lay more eggs and live in the wild for the rest of her short life.

Cecropia eggs – two days old. June 27, 2018.

I kept five eggs and donated the rest to several environmental organizations and a few caterpillar-savvy friends. Three of my eggs hatched on July 4th, ten days after being laid.

Each ¼” black, spiny caterpillar chewed a hole in its leathery brown egg and almost immediately began eating the River Birch leaves I provided.  Within two or three days, the caterpillars outgrew the skin of their initial first stage (instar) and molted into a second instar.  Each time a caterpillar molted, the new skin was “loose” so it could continue its rapid growth. All three ate, grew, and reached the fifth instar, their final caterpillar stage.

While my Cecropias were growing, I got an opportunity to raise another large silk moth.  On July 13, a friend noticed a large moth at the foot of a light pole – a Royal Walnut Moth or Regal Moth (Citheronia regalis).   Unfortunately, the moth was dead but had laid eggs before succumbing.  This hapless moth, like countless others, was drawn to nighttime outdoor lights, but was unable to escape the lights and died.

Of about 25 eggs I kept five and donated the rest to the Academy of Natural Sciences.  Just one of mine hatched and I began feeding Black Walnut leaves, one of its host plants, to the tiny fierce-looking caterpillar.  This caterpillar, known as the Hickory Horned Devil (HHD), is the largest caterpillar species in North America.  This species also goes through five instars before pupating. Although harmless, each stage looks scary and unpalatable, intended to make a bird or other hungry predator steer clear of such a high-protein meal.

To my astonishment, I was raising the moth species with the largest caterpillar along with three caterpillars of the largest moth species.  By the end of August, all three Cecropia caterpillars made their cocoons. My almost hotdog-sized HHD caterpillar turned into a dark brown pupa during the first week of September. This species doesn’t spin a cocoon like its Cecropia relative, but digs down into the soil to pupate and spend the winter.  To simulate an underground environment. I provided an enclosure filled with crumpled paper towels, and the caterpillar pupated there successfully.  When temperatures turned frigid, I moved the HHD pupa into my refrigerator for safe-keeping over the winter.  As I had with their mother, I kept the Cecropia cocoons outside and waited for spring.

All three Cecropia moths eclosed – a male on May 22nd, and females on June 22nd and 25th – and I released them after dark on those nights.

Unfortunately, the HHD pupa died, so that huge, spectacular caterpillar didn’t become a beautiful Royal Walnut Moth as I had hoped.  In nature, less than 5% of caterpillars survive to become butterflies or moths.

Because they are active only at night, it’s rare for us to see Cecropia, Royal Walnut, or other large moths.  However, they and their caterpillars are key food sources for birds and other animals and thus are important members of our local food webs.  You can help keep them flying by providing native trees and shrubs that caterpillars need for food.  If you have outdoor lights, use timers or motion detectors so they are not on from dusk to dawn.  Of course, don’t use pesticides, which kill not just moths and caterpillars, but other beneficial insects, many of which are in steep decline.  If you’d like to see these and other interesting moth species, attend a local moth night event, perhaps  during National Moth Week in July, or have a moth night of your own.  I wish for you a Cecropia Moth, Royal Walnut Moth, and other magnificent nighttime moth wonders!

Welcome Nesting Birds!

By Barb Elliot, PhD

It’s spring, and once again I hear the songs of Northern Cardinals, Tufted Titmice, Mourning Doves, and House Finches as well as the drumming of Downy Woodpeckers and Red-bellied Woodpeckers.  These and other local birds are attracting mates and warning rival males to stay out of newly claimed nesting territories.  At least nine bird species have nested in my yard over the years. As I look back, I remember the joy of seeing birds raise and successfully fledge their young, the heartbreak when things don’t work out so well, and the things I learned along the way.

In early February, 2018, I noticed a male Red-bellied Woodpecker tapping near the top of a dead Black Cherry tree trunk in my yard.  I had left this snag because dead wood is scarce in our tidy landscapes but sorely needed for nesting, feeding, and resting places of birds and other wildlife. Several other woodpecker species – Downy, Hairy, Pileated, and Northern Flickers peck this tree and look under its peeling bark for grubs and other insects. Carolina Chickadees, White-breasted Nuthatches, and Brown Creepers also scour the bark for insect morsels. I was happy to see the Red-belly using this tree to start excavating a nesting cavity.

The Red-bellied Woodpecker worked day after day at this hole in all types of weather, and I was excited to see his progress.  At first he could just fit his head into the hole, but soon got half his body inside, then his tail. Finally he entered the cavity and looked out the hole.  He was joined by a female Red-belly, and they took turns at the work.  One would enter the hole, work inside, and call the mate. The mate then entered the cavity to gather small wood chips and sawdust in its bill and spit them out of the hole. Click here for a 2-minute video of this activity (better viewed on a large screen).

By early May, after more than three months, excavation stopped. In mid-May I saw the female enter with food in her mouth – the baby birds had hatched.  I could hardly wait for nestling Red-bellied Woodpeckers to peer out from the hole!  But alas, it was not to be.  A few days later, the Red-bellies called repeatedly near the nest, but never entered it again.  I understood their agitation when a pair of European Starlings exited the hole.  These invasive cavity nesters had taken over the hole and removed the baby woodpeckers.  Sadly, the Red-bellies’ nesting season was over.

Other cavity nesters have been more successful in my yard. For species that don’t excavate their own cavities, I chose boxes with the dimensions recommended for Tufted

Titmice, Carolina Chickadee, and House Wren, but with entry holes small enough to exclude House Sparrows and European Starlings.  I monitor the nest boxes no more than once a week to minimize disturbing both nestlings and parents.

Over the years, I’ve planted a variety of locally native plants, especially trees and shrubs that support lots of leaf-eating insects, caterpillars in particular.  Ninety-six percent of terrestrial birds in North America feed only insects, spiders, and other arthropods to their young. Even hummingbirds add tiny insects and spiders to their babies’ diet.  Packing more protein than beef, caterpillars are the preferred insect food for feeding nestlings.  Since 90% of caterpillars and other leaf-eating insects specialize on one type or family of plants, I

planted a diversity of native plants to host a diversity of insects.  According to University of Delaware professor Doug Tallamy, to raise a clutch of baby birds healthy enough to leave the nest, a pair of Carolina Chickadees must feed them between 6,000 and 9,000 caterpillars!

Thanks to the native plants in my yard (see list of the 20 most valuable woody and perennial native plants) and the insects they support, Chickadees have successfully raised two broods of five to seven young each over the past 12 years. Tufted Titmice raised one set of five nestlings and House Wrens successfully raised at least eight broods of 5-6 birds each from my nesting boxes.  The importance of native plants to birds’ nesting success is emphasized by a recent 3-year

study of 200 suburban yards in the Washington, DC area.  Scientists from the University of Delaware and the Smithsonian Migratory Bird Center tracked nesting Carolina Chickadees and found that residential yards dominated by nonnative plants did not provide enough insects for birds to raise their young.  Chickadees were successful in raising and fledging young only when at least 70 percent of the plants in a yard were native to the region.  Birds larger than chickadees, such as Red-bellied Woodpeckers, obviously need even more insects and thus a higher percentage of native plants. We should all strive to have more native plants in our yards.

Several cup-nesting bird species – American Robin, Northern Cardinal, Song Sparrow, and Mourning Dove – have also nested in my yard.  Robins nested in a vine, an evergreen tree, on top of a curved downspout, and on top of a wreath hung under my porch overhang.

These birds certainly need native plants to find sufficient insects to feed their young. However, they also require native trees, shrubs, and vines with dense branching and leaves to provide good structure for the nests and concealment from predators.

For example, several pairs of Song Sparrows and Mourning Doves have successfully nested in my Eastern Red Cedars (Juniperus virginiana). These evergreens are dense, hide nests well, are difficult for predators like raccoons to climb, and host more than 40 species of caterpillars.

If you are trying to encourage birds to nest in your yard, here are some tips and lessons I have learned:

1. If you add a nesting box, do a little research to select a box with dimensions for the birds you want, and mount it at the suggested height.

2. Nesting boxes with a predator guard of wood or hardware cloth will make it harder for predators like raccoons and squirrels to reach into the box. A baffle can be added below a box mounted on a pole or wood support.

3. Check a nest no more than once a week. Avoid checking nests when the young are close to fledging.  They may be startled into leaving the nest early and be more subject to predation.

4.  It’s better not to put out nesting material, as birds can find natural materials.  If you insist on providing something, do not put out yarn or hair longer than 2” to avoid entanglement.  Dryer lint, human hair or hair from dogs treated with flea/tick medications should not be used.

5. Check your yard for any plastic that birds may use as nesting material. A healthy baby Robin perished in a local nest when a plastic strip used in the nest wrapped around its leg and prevented it from flying from the nest.

6. If a baby bird without feathers is on the ground, return it to the nest. However, a baby bird on the ground that has feathers likely has parents nearby. Many newly fledged young spend time on the ground and are fed by parents for several days after leaving the nest.

7.Leave cats indoors year round to prevent killing of babies and adult birds.

 

8. Don’t use pesticides or herbicides. Birds and other wildlife in a healthy habitat will keep insects in balance.

9. Avoid trimming shrubs and trees during nesting season.

10. At the end of the season, clean out nesting boxes. This allows birds to use the box for roosting and cuts down on blowflies and other insect parasites that may prey on future nestlings.

Above all, enjoy the birds that visit and nest in your yard!  If you have (and keep adding) native plants, you can be assured that there will be enough food for them to successfully raise their young.

Native Vines for Beauty and Wildlife Value

 By Barb Elliot

Vines have a bad rap. Invasive non-native vines like Kudzu, Oriental Bittersweet, Japanese Honeysuckle, Porcelain Berry, and English Ivy grow up and over trees, often smothering whole forest edges.  By making them top-heavy, these vines can damage and pull down entire trees.  However, not all vines are bad actors.  Most locally native vines are attractive and well-behaved.  By providing food, shelter, and nesting places, they add high wildlife value to our habitat gardens.  I have three of these natives and I highly value the roles they play in my garden.

Trumpet Honeysuckle, Lonicera sempervirens

With Trumpet (aka Coral) Honeysuckle in your yard, Ruby-throated Hummingbirds will visit – guaranteed!  This native honeysuckle is not at all like its unruly cousin, Japanese Honeysuckle. Handsome and well-behaved, this vine sports blue-green foliage and coral-red trumpet-shaped flowers.  It’s easy to grow in average, well-drained soils with medium moisture. A twining 10-15’ vine that needs a support, it is striking on a fence or trellis with its profusion of flowers.   It grows in shade, but flowers best in full sun.  Trumpet Honeysuckle begins blooming in April or May and blooms intermittently through summer and into the fall.  In autumn, birds eat the red berries.

Trumpet Honeysuckle provides food, shelter, and nesting locations.  One year, American Robins built a nest in one of my honeysuckle vines.  A vine growing close to my bird feeders provides shelter for birds escaping hawks and other predators. According to Doug Tallamy, this honeysuckle hosts up to 33 species of butterfly and/or moth caterpillars that eat its leaves.  Among them are two day-flying hummingbird look-alike moths. the Hummingbird Clearwing and Snowberry Clearwing.

Trumpet Honeysuckle is truly beloved by hummingbirds.  I love to sit on my deck and watch these flying jewels sip nectar from the long tubular flowers and even fight over the blossoms.  George Washington grew this vine at his Mount Vernon estate where it is still grown today.  In a 1785 diary entry, Washington described planting it around columns and along walls.  Perhaps he, too, enjoyed the hummingbirds that visited his Trumpet Honeysuckle.

Virginia Creeper, not to be confused with Poison Ivy, is a beneficial vine that’s entirely harmless to humans.  To differentiate the two plants, look at the leaves. Poison Ivy always has 3 leaflets per leaf,  but Virginia Creeper has 5 leaflets. Some young Virginia Creeper vines may have a few leaves with just 3 leaflets, but most leaves will have 5 leaflets.  The green leaves are handsome and in full sun turn bright red or purple in October.

Offering high wildlife value, Virginia Creeper hosts 32 species of caterpillars, including the striking Pandora Sphinx and Abbott’s Sphinx moth caterpillars.  These are my most sought after caterpillars, but I have yet to find either of them.  However, as a consolation, I’ve discovered several Virginia Creeper Sphinx moth caterpillars, which I raised to become beautiful adult moths.

In spring, the wildlife-friendly Virginia Creeper’s inconspicuous flowers attract bees and other small pollinators.  Thirty species of birds, including chickadees, woodpeckers, robins, catbirds, warblers, and bluebirdsrelish the dark blue berries in autumn.  Reddish fall foliage and the bright red stems of the berries lure the birds.  Small animals use this vine for cover, especially when it grows along the ground.  A few years ago, Northern Cardinals built a nest in the Virginia Creeper growing on my arbor.

A deciduous woody vine, Virginia Creeper is easy to grow in full sun to full shade in well-drained soil with average moisture.  It will climb brick or stone walls, trellises, arbors, fences, or large trees. One of my favorite ground covers, it will happily cover a stump or wood pile. Although a vigorous grower, climbing 30’ feet or more, it will not smother trees.  If it becomes unruly, it can easily be pulled down or cut off at the base where it will re-sprout.

Virgin’s Bower, a native clematis, is a superb plant for pollinators.   Its small white flowers have a pleasing, sweet fragrance and cover the foliage from mid-to late-August into September.  The flowers attract many pollinators, including butterflies, bumble and other native bees, plus interesting wasps and flies.  Intent on collecting nectar and pollen from the flowers, they are usually oblivious to my presence.

Predators like spiders and centipedes furtively wait to catchthe unsuspecting pollinators. I have spent hours, both day and night, watching the pollinators and dramas of nature play out on Virgin’s Bower.

Virgin’s Bower is very easy to grow in medium to wet well-drained soil in part shade to full sun.   Although I love this vine, it is not for the faint of heart. It is a vigorous grower, and if given support, will climb to 20’.  When growing along the ground. it can spread into a tangled

mass.  The vines can take root where they touch the ground.  Seeds from its attractive seed heads are windblown, so new plants can pop up elsewhere in your yard.  But if you are diligent and keep this vine in check, you and many pollinators will be well-rewarded by your efforts.

Now is a good time to add these vines to your landscape.  If you have a small space, Trumpet Honeysuckle will work well.   For larger areas, try Virginia Creeper or Virgin’s Bower.  These vines will add texture and interest to your landscape. Pollinators, birds and other wildlife will thrive in your garden.

Prime Plants for Nature: Backyards for Nature 2018 Native Plant Awards

 

By Edie Parnum

Every year we feature two superior native plant species.  One of the Prime Plants for Nature is a Tree, Shrub, or Vine and the other is a Perennial.  Prime Plants are selected based on these criteria:

  1. Native to southeastern Pennsylvania.
  2. Offer high wildlife value and contribute significantly to your property’s web of life.
  3. Provide food for wildlife by producing nutritious fruits, seeds, nuts, nectar, or pollen. Most host insects that are eaten by birds or other animals.
  4. Offer shelter and places to raise young.
  5. Easy to grow and make an attractive addition to your landscape.
  6. Sold at native plant nurseries and native plant sales.

Our selections for the 2018 Prime Plants for Nature awards are:

Spicebush Swallowtail Butterfly caterpillar.  In fact, this caterpillar species is entirely dependent on Spicebush and its close relative, Sassafras, for its sustenance. Spicebush is also a host plant for Eastern Tiger Swallowtail and Promethea Moth. The flowers are pollinated by small native bees, wasps, beetles, and flies.

Growing Conditions:  This fast-growing, disease-free shrub will thrive in a variety conditions from semi-sun to shade in average to moist soil.  Its natural habitat is the understory of moist woodlands or woodland edge. The leaves, twigs, and other plant parts are spicy when crushed, so deer don’t usually browse this shrub.

Appearance: The Spicebush is a multi-stemmed 6-12’ deciduous shrub. Its blossoms appear in early spring before the foliage emerges. Although the flowers are small, they create a nice show of yellow haze when little else is blooming. Because this shrub is dioecious, male and female flowers occur on separate plants, and the berries form from female flowers. The fall foliage is yellow.

Wildlife Value: Purple Coneflower’s pollen and nectar are magnets for many bees and butterflies.  Bumble bees and short and long-tongued bees such as small carpenter, sweat, long-horned, digger, and mining bees plus long-horned beetles visit the flowers. Butterflies such as swallowtails, sulphurs, fritillaries, Red Admiral, American and Painted Ladies, Monarch, and skippers are attracted also.  Crab spiders may lurk in the flowerheads to capture both beneficial and pest insects.   A few moth caterpillars will eat the flowers and leaves including Blackberry Looper, Camouflaged Looper (adorns itself

with flower parts to avoid predators), Common Pug, and Sunflower Moth.  In late summer and fall the coneflowers’ seeds are eaten by American Goldfinch and other finches.

Cultivars of Purple Coneflower are frequently sold. When purchasing plants, if possible, choose straight native species. Some cultivars selected by breeders change the shape or color of the flowers and possibly reduce the amount of pollen and nectar. For instance, Purple Coneflower ‘Pink Double Delight’ with its double flowers is less attractive to pollinators.

Growing Conditions:   This trouble-free perennial grows in moist to average soil with sun or part sun.  It can survive heat and moderate draught drought conditions.  Because it prefers lean, poor soil, fertilizer and other amendments are not recommended. The parent plant produces seedlings that can be easily transplanted.  The roots of 3-4-year-old plants can be divided and transplanted, too. Normally, neither deer nor pests are a problem.

Appearance: Purple Coneflower with its pinkish-purple flowerheads is one of our prettiest native perennials.  It grows 3-4 feet tall on sturdy stems that do not require staking.  This perennial blooms from July-September.  Cutting back the spent flowers can extend the blooming period.

A Note of Caution:  Many retailers sell plants treated with pesticides containing neonicotenoids.  These long-lasting pesticides are absorbed into the entire plant.  Insects eating the pollen, nectar, leaves, or any plant part are poisoned. According to the National Wildlife Federation, neonics are “found in hundreds of products, including sprays, granules, tree injections and soil drenches (pesticides applied to the base of plants).”  To avoid neonics, “carefully read labels. Steer clear of products that contain imidacloprid, acetamiprid, dinotefuran, clothianidin or thiamethoxam.”  If it’s not apparent that plants are neonic-free, before you buy, ask the seller to verify that neither they nor their grower treat plants with neonics in any way, including growing them from neonic-coated seeds.  See https://www.nwf.org/Magazines/National-Wildlife/2018/Feb-Mar/Gardening/Nixing-Neonics

 

Polyphemus Moths Live Near Me

By Edie Parnum

A Polyphemus moth alighted on my walkway.  It was August 2016, and I had just moved to a retirement community.   This cinnamon-colored giant silk moth had a wingspan of 4 1/2 inches.  Each hind wing had a large eyespot highlighted with yellow and blue.  It’s named for Polyphemus, the one-eyed Cyclops, who was blinded by Odysseus. Although I’m a “moth-er”, I had never seen this handsome moth before.

This summer I acquired two Polyphemus caterpillars at Mothapalooza, a mothing

conference.  They survived the 9-hour ride from southern Ohio.  Once home, I fed them White Oak leaves from my community’s wooded area.  They ate voraciously and pooped continuously.  (Scientists call the excrement frass.)  Once or twice a day I cleaned out the mesh cage and supplied them with fresh leaves.  After two weeks, they stopped eating and formed their cocoons.

Twelve days later, a beautiful Polyphemus adult emerged.  I knew she was a female because she had unfeathered antennae.  Some friends and I released her at dusk.

Off she flew beaming out her pheromones to attract a mate.  Two days later a male emerged from the second cocoon.  We released him, too.  Using his feathered antennae, he can “smell” a female’s pheromones from miles away.

These two moths (or others of their species) will meet up and mate.  They will not eat.  Their sole job is to mate. The fertilized female will lay her eggs on an oak, willow, maple, or birch.

Her eggs will hatch and become caterpillars.  Birds, mammals, and other insects will eat most of them.  Miraculously, a few will survive.  The cycle of life will continue—cocoon, adult moth, mating, egg laying, tiny caterpillars, big caterpillars, and cocoon again.  This will happen over and over, as long as we have wooded areas or yards with the essential native trees to support them.

Fall can be a good time to look for Polyphemus and other caterpillars. Many caterpillars leave the host plants where they’ve been feeding and start walking.  These “wanderers” are looking for a suitable place to overwinter.  Many will spend the winter in leaves on the ground; others will spin a cocoon attached to a twig.

A Polyphemus moth cocoon could spend the winter in your own yard. Never mind the cold.  Go out into your yard and examine the bare branches of your native trees and shrubs. In 2012 Barb Elliot found a Polyphemus moth cocoon on a Spicebush twig.  She told her story on our blog: https://backyardsfornature.org/?p=87, “A Magnificent Moth”.  Maybe you, like Barb, can find a Polyphemus or other cocoon. At all times of the year, we can look for signs of nature, both active and dormant, in our backyards.

Pollinators Come to a Tiny Urban Yard

By Edie Parnum

A 130-square foot cement-covered backyard —who would expect such a yard could be a haven for wildlife?  The property is on a narrow street of rowhouses in Philadelphia.  The nearest park is several miles away. Nonetheless, this garden is teeming with  butterflies, bees, wasps, moths, and a host of other pollinating insects.

Navin, an avid amateur naturalist, moved to this property last fall.  He saw the potential to attract pollinators with native plants in raised beds and containers.   In early spring, he invited me for a Backyards for Nature consultation.  Together we made a list of short and mid-sized perennials that bloom from early spring to late fall and are known to attract a variety of pollinators.

He purchased good quality plants from Good Host Plants, a native plant nursery in Philadelphia. He planted perennials in two raised beds that sit atop the cement.  Others he planted in large, deep containers. He installed two trellises for growing vines.

It worked.  In the spring bees and other insects found the Wild Columbine (Aquilegia canadense), Beardtongue (Penstemon digitalis). and Creeping Phlox (Phlox subulata).  The summer blossoms of Swamp Milkweed (Asclepias incarnata), Butterfly Weed (A.tuberosa), Purple Coneflower (Echinacea purpurea), Joe-Pye Weed (Eutrochium purpureum), Dense Blazing Star (Liatris spicata), Cardinal Flower (Lobelia cardinalis), Wild Bergamot (Monarda fistulosa), Short-toothed Mountain Mint (Pycnanthemum muticum), and Orange Coneflower

(Rudbeckia fulgida) host many butterflies and other pollinators.  The show continues this fall with Grey Goldenrod (Solidago nemoralis), New England Aster (Symphotrichum novae-angliae), and other asters.  Trumpet Honeysuckle (Lonicera sempervirens) and Virginia Creeper (Parthenocissus quinquifolia) will bloom on the trellises.

On weekends Navin observes and photographs the wildlife in his

garden.  He discovered Monarchs laying eggs on his Swamp Milkweed.  An insatiable predator, a Carolina Mantis (our native mantid species) lurked nearby, so he decided to bring the Monarch eggs and caterpillars inside to raise them in safety.  So far, he’s raised and released 34 adult Monarchs.  An additional 47 are either chrysalises or caterpillars and will be released soon for their journey to Mexico.  He’s also rearing BlackSwallowtail eggs and caterpillars that grow on parsley.  According to Navin, nighttime is the best time for spotting the small eggs and caterpillars.

So far, he’s recognized ten additional butterfly species including Eastern Tiger Swallowtail, Red Admiral, and Eastern Tailed Blue.  The biggest surprise was a Giant Swallowtail, a southern species rarely seen in

the Philadelphia area. Other insects are finding his garden, too.  Navin observed a Snowberry Clearwing, a large day-flying moth, nectaring on blossoms like a hummingbird. A variety of bees, wasps, flies and moths feed on nectar and pollen.  With so many insects, predators such as the Carolina mantis as well as spiders,lacewings, and parasitic wasps have located his yard, too.  One day he spotted a lacewing eating aphids.

Navin offers advice to other wildlife gardeners with limited space.   A great many plants can be crowded into small garden plots, raised beds, and large, deep containers.  Prune the plants periodically to keep them short and use stakes before tall plants get floppy. Water frequently in hot weather.

Navin submits his wildlife sightings to iNaturalist, a nature record-keeping app.  He photographs the butterflies and moths (both adults and caterpillars), bees, wasps, flies, beetles—in fact, any creature using his plants.  He uploads these photos and the species names to iNaturalist. The dates and location are automatically included.  When the species is unknown, iNaturalist experts can usually provide the identification.  Scientists and other amateur naturalists can view and study Navin’s sightings and those of the other 137,000 iNaturalist users.

How do so many creatures find this yard?  Certainly, adult butterflies and moths can fly.  They’re wired to find nectar and pollen for their survival.  With their chemical sensors, they can also locate the specific plants they require to lay their eggs.  Other insects have powerful search mechanisms, too.

Navin will keep searching.  He’ll find more creatures.  After all, this garden is only 6 months old.

Prime Plants for Nature: Backyards for Nature 2017 Native Plant Awards

by Edie Parnum

Every year we feature two superior native plant species. One of the Prime Plants for Nature is a Tree, Shrub, or Vine and the other is a Perennial. Prime Plants are selected based on these criteria:

1. Native to southeastern Pennsylvania.
2. Offer high wildlife value and contribute significantly to your property’s web of life.
3. Provide food for wildlife by producing nutritious fruits, seeds, nuts, nectar, or       pollen. Most host insects that are eaten by birds or other animals.
4. Offer shelter and places to raise young.
5. Easy to grow and make attractive additions to your landscape.
6. Sold at native plant nurseries and native plant sales.

Our selections for the 2017 Prime Plants for Nature awards are:

Trumpet Honeysuckle, Lonicera sempervirens

nourishes our Ruby-throated Hummingbirds. Butterflies and bumblebees use the nectar and pollen. As with other native plants, the foliage is food for native caterpillars, including Spring Azure butterflies and moths such as Hummingbird Clearwing (Hemaris thysbe), Snowberry Clearwing (Hemaris diffinis), Harris’ Three-spot (Harrisimemna trisignata), and Great Tiger Moth (Arctia caja). These caterpillars in turn are food for birds and their nestlings. Songbirds occasionally eat the red berries.

Aster flowers. Sweat bees, leafcutter bees, carpenter bees, mining bees, and bumble bees are attracted to the blooms’ bold, contrasting colors. The flowers are an important nectar source for Monarch butterflies during their fall migration. The foliage hosts 109 species of caterpillars (per Doug Tallamy, Bringing Nature Home: How You Can Sustain Wildlife with Native Plants, 2007) including the Pearl Crescent butterfly. Moth species include Saddleback caterpillar, several geometers, and Brown-hooded Owlet.

of brightly colored blossoms, each 1 ½” across, appears in late summer and persists until fall. The flower rays are bright pink or purple, the central florets yellow-orange. The plant grows 3-6 feet high and may require staking. In a small garden, keep the plant from getting too tall by pinching back the top growth in early June and then again in early July. The flowers are attractive additions to flower arrangements. Cultivars are available in a variety of colors and heights.

Growing Conditions: Adaptable to a variety of situations, sun or part sun, dry to moist soil.  Seedlings can be transplanted.

Appearance: Medium to large fast-growing deciduous tree with dark, peeling bark.  White flowers bloom in May on drooping stalks called racemes.  The reddish-black fruits ripen in late summer.

Cardinal Flower, Lobelia cardinalis 

Wildlife Value: If you want to entice hummingbirds to your yard, this is a must-have perennial.  Ruby-throated Hummingbirds are attracted to the Cardinal Flower’s brilliant red flowers and are its primary pollinators. The nectar is very sweet, twice as sweet as a soda.  A hummingbird’s bill is long enough to reach the nectar deep inside the tubular

flower.  The feathers on the head pick up the pollen and carry it from one plant to another. Cardinal Flowers bloom for six weeks in the late summer during the hummingbirds’ southbound migration. Bees rarely visit these flowers because their proboscis is too short to access the nectar.

Large swallowtail butterflies can reach the nectar with their long proboscis but are unable to pick up and transfer the pollen.

Growing Conditions:  Cardinal Flower is a trouble-free perennial that enjoys moist soil.   It will grow in average soil in a shady location. Not a true perennial, the plant and roots die after the growing season. However, the next spring it produces off-sets that will flower or can be transplanted to new locations.  The parent plant also produces seedlings that can be transplanted.  In the late fall, lay the flower stalk on the ground where you want seedlings to sprout in the spring. Appearance:  The striking red flowers are arranged along 8” spikes called racemes.   The plant grows 2 ½ -3 feet high.  The flowers are attractive additions to flower arrangements.

Remembering Nature Discovery Day

By Edie Parnum

For eight years I have been gardening for nature on my ¾-acre suburban property. My yard with its abundance of native plants teems with birds, butterflies, bees, beetles, moths, and other creatures both big and small.  On August 29 my property abounded with people, too.  I had invited nature-loving friends to enjoy my native plants and discover the creatures they support.

Some people came for just an hour, others stayed all day.  Most participated in one of the three guided yard tours.  The insect and pollinator walks were popular, too.  Kids enjoyed their own nature and insect events.  A sizable group drove to Barb Elliot’s nearby property and saw her pond and thriving native plant habitat.  Some truly nature-crazed individuals stayed after dark for moth night.

Unquestionably, the native plants were a hit. All the species were labeled for easy identification. Many of my favorite plants (Short-toothed Mountainmint, Grass-leafed Goldenrod, Upland Ironweed, Cardinal Flower, Great Blue Lobelia, Garden Phlox, Trumpet Vine, Trumpet Honeysuckle, Large-leafed Aster, and Sneezeweed) were in bloom. Berries on woody plants (Nannyberry and Blackhaw Viburnums, Flowering and Silky Dogwoods, Winterberry Holly, Black Chokeberry) and a vine (Virginia Creeper) were ripe and ready for the fall migrants.   (Click here for my complete yard plant list.)

Insects attracted notice and won new converts.  Many admired the Monarch and Black Swallowtail caterpillars.  The pollinators were active on the flowers.  We saw native bees (European Honey bees, too), wasps, flies, beetles, day-flying moths, as well as Ruby-throated Hummingbirds spreading pollen while feeding on the nectar.   Our entomologist, Dan Duran, PhD, identified a large blue-winged wasp (Scolia dubia) nectaring on mountainmint.  This wasp, a parasite on the larvae of Japanese Beetles, is now a favorite of mine.

The sharp-eyed kids on Debbie Beer’s nature walk saw a migrant American Redstart.  By turning over rocks and logs, they discovered slugs and other creepy-crawlies. They also found spiders (the wolf spider was popular), beetles, and a cicada shell—goodies the adults missed.

Vince Smith gave us a geology lesson.  My property is composed of Precambrian gneiss and schist, one of the oldest soils on the planet.  Because it’s well-drained, the Tulip Poplar, Black Gum, and various oaks I’ve planted will develop deep roots.   They should become massive trees and provide wildlife value for decades, perhaps centuries.

Usually I merely write about my yard’s plants and animals and post photos on the Backyards for Nature blog.  However, neither words nor pictures are enough.  Seeing the natural beauty of my yard and discovering the creatures living there is more powerful.

Many people told me they were inspired to create their own backyard ecosystems.  Others vowed a renewed commitment to enhance their developing habitats.

They said Nature Discovery Day was fun. I could see it on their smiling faces.
