Wildlife Wednesday: Eastern Black Swallowtail

Novembr 27, 2018, I spotted two tough little Eastern Black Swallowtail cats munching on a lone fennel plant, left in a cleared out bed at the Williamsburg Botanical garden.

~

Eastern Black swallowtails lay their eggs and their larvae feed on parsley and fennel. This bed was filled with Lantana, Salvia, and with fennel all summer, and hosted many butterflies from May until November.

~

Butterflies covered this planting of Lantana at the Williamsburg Botanical Garden in August.

~

~

When I told my friend Judith about the caterpillars, she came and rescued them the afternoon before a hard freeze, at the very end of November.

~

Judith cared for the caterpillars until each formed its chrysalis, feeding them organic parsley in little habitats indoors; then she added them to her collection of living chrysalides. She cared for the sleeping caterpillars all winter and brought them over to our garden yesterday morning,  just as they were ready to leave their chrysalides as butterflies.

~

She named the two caterpillars rescued from the fennel at the botanical garden ‘Rough’ and ‘Tough’. They spent the winter pinned to this Styrofoam in her butterfly habitat.

~

A total of three Black Swallowtail butterflies emerged during her visit yesterday morning. She generously set all three free in our garden. There were two males and a female. The amount of blue on the hindwings is the main way to distinguish gender in these swallowtail butterflies.

~

Here Judith is releasing the first of the butterflies, a female. Then she invited us to help release the other two butterflies into the garden.

~

~

The butterflies need some time for their wings to fully stretch, dry and toughen before they are ready to fly. We were able to hold and observe them as they prepared for their first flight.

~

Would you like to attract butterflies to your garden?

The first step is to plant a variety of both nectar plants and host plants.  Nectar plants attract butterflies, and host plants allow them to lay their eggs and will feed the larvae as they grow.

If you attract butterflies and host their larvae, it is important to commit to not using insecticides in your garden.  Yes, the larvae will eat some leaves on their chosen host plant.  The plants will survive.

~

~

Fennel and parsley host several types of swallowtail caterpillars.  Other easy to grow host plants include oak trees; spicebush, Lindera benzoin;  paw paw trees, Dutchman’s pipevine, Aristolochia macrophylla; passionfruit vine, Passiflora lutea; and even common wood violets.

Most butterflies prefer very specific host plants and may only use one or two.  For example, Monarch butterflies want Asclepias, or milkweed.  There are several different species of Asclepias available, and most all of them will support Monarchs.

It is useful to do a little research on common butterflies that live in your own region, and then plant their host plants, if you don’t have them growing on your property already.

~

This was the last of the three butterflies to emerge from chrysalis, and the last to be released. He wasn’t ready to fly, and so we gently placed him on this red bud tree, where he rested while his wings hardened. Finally, he also flew away into the garden.

~

Butterflies need safe places to shelter out of the wind at night and during storms.  Trees and dense shrubs serve them well.  They also need places where they can ‘puddle,’ landing on the ground to drink water from mudpuddles, moist earth, or even shallow saucers filled with gravel and water.  Butterflies need the minerals they absorb this way.

Butterflies will feed from a variety of nectar plants, including trees, vines, and flowering plants you may plant in baskets, pots or beds.  Lantana is an absolute favorite source of nectar.  Agastache, anise hyssop, attracts even more butterflies than Lantana!  All Verbenas attract butterflies and are very easy to grow.  The more flowers your garden offers, at a variety of heights, the more butterflies will likely stop by to visit your garden.

~

We have seen a variety of butterflies in our garden already this spring, including Black Swallowtails. In fact, an hour or so after the release, we saw another Black Swallowtail laying eggs on an emerging fennel plant in the upper garden. This is one of the butterflies we released, resting before its first flight,

~

There are many butterflies and moths native in Virginia and all of them are currently in decline. We have a network of dedicated butterfly enthusiasts in our area who rescue and raise cats, releasing the butterflies into the wild as they emerge. By protecting the butterfly larvae, they help insure that more individuals make it to the adult butterfly stage, mate, and increase the population.

~

One of the greatest problems faced by butterflies is loss of habitat.  The native plants they depend on to raise their next generation are often the ones removed for development, but not replanted by landscapers.

Gardeners can make a significant difference by providing a small bit of habitat in their own yard.  Like a patch in a quilt, our own bit of habitat may be small.  But, when many of us are all working together, we can provide safe places for butterflies to rest and refuel along their migration routes, and can provide safe and welcoming places for them to lay their eggs.

~

~

By working together, each of us providing a bit of habitat and safety for butterflies, we can help support the next generations of butterflies; making sure that our own grandchildren can enjoy these beautiful insects and share their magic with their own children, far into the future.

Will you join us?

Happy Birthday? Eastern Black Swallowtail

~

What a treat to discover a newly emerged Eastern Black Swallowtail butterfly while working in our garden today.   I was a little surprised to notice that this butterfly was clinging to a stem and not a flower, and didn’t move as I trimmed the grass nearby.  It took a moment to register that it was still clinging beside its now empty chrysalis and just beginning to stretch and dry its wings.

Our newly emerged butterfly clung to a stalk of chives, a ready food source once he or she is able to climb up to the flowers.  Right across the path, lots more cats were still happily munching the bronze fennel!

~

~

We plant the fennel hoping to witness this beautiful display each year.  A perennial, it will put out some new growth within a few weeks.

I’m not sure whether this butterfly is a male or female, as I didn’t get a photo of its wings spread from its dorsal side.  It was still seeing the world anew and adjusting to life with wings!  I’ll hope to spot and photograph is individual again in the coming days.

~

~

If you intend to attract butterflies to your own garden, please remember to abstain from using any insecticides and follow organic gardening principles.  Provide host plants for the species you hope to attract, and offer plentiful nectar plants, wet earth where the butterflies can ‘puddle’ to drink, and trees where they can seek shelter.

Many folks these days want to plant lots of milkweed to attract butterflies.  Please keep in mind that the only common butterfly species in our area to use milkweed, Asclepias species, as a larval host is the Monarch.  Other popular host plants, especially for swallowtails, include dill, parsley, fennel, spicebush, rue, Queen Ann’s lace, wild cherry, poplar, apple, ash, and Dutchman’s pipe.

Happy butterfly gardening!

Wildlife Wednesday: Eastern Black Swallowtail Cats

Eastern Black Swallowtail larvae feast on our bronze fennel.

~

Hummingbirds are much smarter than we want to consider.  They would have to be.  How else would they know to buzz in for a sip of nectar when my camera is out of reach?

The first of the morning zoomed by to visit a basket Verbena and Lantana flowers warmed by early morning sunshine on our deck.  I’d gone out with the cat to water first thing, before the day’s heat had a chance to build.

Even had I brought the camera out with me, the little guys would have likely buzzed away again before I could even turn it on.  They are independent minded like that!

~

~

I heard their comings and goings a bit later in the garden.  My attention was focused on some late season planting and mixing up snacks of fish emulsion for the pots, and I was too busy to fumble off my gloves and pull the camera from my pocket.

The hummers could care less; they were systematically sampling the morning’s offerings of nectar.

~

~

It was early afternoon when I realized they weren’t as innocent as I’d assumed.  My partner and I were headed out on errands.  Two hummers lingered at the top of the drive, as though to wave us ‘Good-bye.’

One lit on a branch to watch the car pull away while the other made a dash for the Lantana patch that grows by the street.  Their message was clear: they would watch over the place while we were away.

~

A female Eastern Black Swallowtail butterfly enjoyed nectar from Lantana last Sunday afternoon.

~

A new friend asked me over the weekend whether I photograph many birds.  Questions like this leave me a bit on the defensive.  I’m not much good with birds, especially with hummingbirds.

I’ve taken maybe five good photos of hummingbirds over the past several years.  They always seem to take off before I can get my camera out and on and focused on them.  They seem to have a sixth sense about when I’m paying attention to them, and quickly lift up and away.

~

~

Maybe I should set an intention to capture more bird photos in the weeks ahead.  The big ones, like eagles and herons are slow and patient enough for me.  I’m always happy to snap their portraits.  It’s the fast little ones that I’ve not yet learned to charm into posing.

So now you know the real reason why I’m thinking and writing about hummingbirds, while sharing photographs today of caterpillars.

~

~

Caterpillars make easy targets for a novice wildlife photographer.  They are so entirely focused on stripping the vegetation from the fennel that they pay me and my curious camera no mind.

These beauties are Eastern Black Swallowtail larvae, and they enjoy a variety of host plants related to herbs in the carrot family.  They love parsley and dill, fennel, Queen Anne’s lace, and wild parsnip.  I counted four individuals on a single fennel plant this afternoon, after finding only a single cat munching away yesterday.

Eastern Black Swallowtails may produce three generations over our long summer.  Depending on the weather and the host plants, an individual may develop from egg to adult in 40-60 days.  The final generation of the summer may overwinter here as a pupae.  This beautiful butterfly may be found in Eastern and Central North America from Southern Canada south to Northern Mexico.

~

~

We don’t mind them munching the herbs.  We plant the herbs in hopes of attracting them and keeping them returning to our garden.  Besides, the herbs are tough, and will send out new growth so long as we keep them hydrated.

~

How many cats can you spot on the fennel?  They blend in very well.

~

That may sound like a strange thing for a gardener to say.  But as much as I admire the beautiful plants in our garden, it feels very lonely and empty without the hum and buzz and movement of the many animals who share it with us.   The garden is like a living stage; and it’s the animals, even the insects, who bring the drama to life.

that they depend on is being destroyed.

Our hummers love this Salvia ‘Black and Blue.’  Goldfinches love the black eyed Susans.

~

We’re willing to sacrifice the herbs in hopes of enjoying the butterfly adults!  We plant lots of nectar plants to occupy the butterflies (and hummingbirds) while we enjoy them.

That said, I couldn’t find a single butterfly when I was out with the camera in late afternoon.  My partner said he saw a big yellow Tiger Swallowtail, that I missed.

The best I could capture on this Wild Life Wednesday was a tiny dragonfly, a large bumblebee, some unknown bugs on an Iris seedpod, and this family of swallowtail cats.

That’s OK.  I know they’re out there, and that means the garden is a refuge and delight for many amazing species.

Home For Some Swallowtails

~

We are a lot like little kids when we head out to the garden.  We get such a kick out of watching the butterflies, and their beautiful psychedelic ‘teenaged’ caterpillar families.

The family portrait here shows you a female Black Swallowtail butterfly feeding on fennel flowers.  I believe the caterpillars are also Black Swallowtail larvae.

~

~

While the adult butterflies float around from flower to flower, the caterpillars largely stay put as they slowly move along the branches of our fennel, eating as they go.  Not to worry… the fennel grows back very quickly, shooting out lots of new stems, leaves and flowers.

I was fortunate to find four beautiful pots of bronze fennel on a clearance sale today at The Great Big Greenhouse in Richmond.  I’ll be adding these new fennel plants to the garden in the morning, knowing they will come back even bigger and stronger in the spring.

~

~

These caterpillars may seem a little brazen in their conspicuous gnoshing.  They love fennel, carrots, parsley and parsnips.  Whatever substances they ingest from these leaves, it leaves them tasting foul.  The birds show little interest in them.

~

Black eyed Susans, Rudbeckia hirta, attract many different butterflies.  Goldenrod, Solidago, (top right corner) will soon bloom, attracting many hungry pollinators.

~

There are plenty of wildly safe places in our garden for them to withdraw when ready to form their chrysalis.  We rarely notice one, anyway.  But oh, the gorgeous butterflies which fill our garden in late summer!

“Feed them, and they will come.”  No need to run to Pet Smart for a big expensive bag of something.  No, just plant nectar rich flowers.  If you fill your garden with the flowers they love, and have a few herbs around to receive their eggs and feed their larvae, then you, too can create a haven and home for the swallowtails.

~

Garlic chives and Rudbeckia have both naturalized in our garden. These clumps seeded themselves as neighbors, forming a little  ‘food court’ for pollinators.

~

But if you choose to attract and support pollinators, please do so consciously and responsibly.  What do I mean?

Find a way to garden without using herbicides or insecticides which will poison these fragile, and often endangered creatures.  Yes, you will have some leaves chewed by insects.  Yes, you will have to weed by hand.

~

Why is the Columbine blooming in August??? We are grateful for the blessing. The nibbled leaves hardly detract from the lovely flowers.

~

Yes, you may have some unsightly foliage here and there. 

But it is well worth it to enjoy a garden filled with life.  Not only do we enjoy the spectacle of summer butterflies, but we also have many pairs of nesting birds, sustained by the rich insect life in our garden.

~

Basil is a one of my favorite annuals in our garden. Not only is it beautiful and up to our muggy climate, it also attracts many pollinators. Goldfinches love its seeds. It works beautifully in flower arrangements, and can still be harvested for summer cooking.

~

Every garden has a purpose.  Every gardener has to have a purpose in mind when building her garden.

Ultimately, we expect the garden to bring us pleasure as it entertains us, gives us purpose each day, helps us stay fit, and gives us another reason to go shopping.

~

Echinacea and Basil have proven a stunning combination this summer.  The Echinacea’s seeds will feed lots of happy birds this autumn.

~

We decided early on that this garden would do all of those things, but also provide a home for pollinators and birds.

Home means safety and food; a place to rest; a place to lay eggs and raise young; clean water to drink.  A puddle, birdbath, or even a wet dish of sand will suffice.

Little did we know that the birds would help us plant.  We never expected the lizards, turtles and birds to help control the insects.  We have bees to pollinate the fruit, and butterflies to watch on summer afternoons.

~

And little did we realize how much happiness flows from creating a home for some swallowtails.

Eastern Black Swallowtail Caterpilliars- Revisited

The first chrysalis turned up a few days ago. Perhaps you saw my post on the caterpillars?  So far we found one chrysalis on the bronze fennel the caterpillars were munching, and another on a nearby tomato cage. The others must be close, but I haven’t found them yet.  Originally there were nine caterpillars on … Continue reading

Hungry Caterpillars; What’s For Lunch?

Bronze Fennel is a favorite of Black Swallowtail butterfly caterpillars I counted nine caterpillars on just one fennel plant this morning Hungry as the caterpillars might be, fennel grows quickly and will survive their munching.  This Osmanthus goshiki shrub doesn’t look like a good host plant, but is on the menu for this gigantic beast. … Continue reading
