Summer’s Last Swallowtails

In the final weeks of September, one of the butterflies emerged with damaged wings. She couldn’t fly, so I kept her in the caterpillar habitat and gave her fresh clippings from the butterfly bush every day.

Sometimes I took her out of the enclosure and carried her around the yard, letting her sample marigolds and lantana and salvia.

When she died, a day or two before her two-week birthday, she had undeniably lived longer than she would have lived in the yard. But was it enough?

Was nectar enough, or did my butterfly regret her flightless wings and unfertilized eggs?

What does a butterfly, or a caterpillar, need from life?

Caterpillar Sept 28

Do they yearn for sunshine and plentiful food? Do they crave happiness? Do they grieve?

There’s a poem hiding in these questions, but it’s so well hidden that I can’t find where it starts. Not today, anyway. Not with a rainy cold front outside and a miserable cough inside.

My last swallowtail caterpillar molted into a chrysalis yesterday. Now I have twenty-five chrysalises ready for winter.

It’s an interesting idea, sleeping through winter. What if I could simply set my alarm for “spring” and call my blankets a chrysalis? On days like today, cough and all, it seems like a good idea. But what about snow? And holidays? Would I be sad, in the spring, that I had missed them? Would you?

Zebra Swallowtail Butterfly

Zebra Swallowtail August 30

Yesterday a new species of swallowtail butterfly visited the yard. This zebra swallowtail stopped a while to explore the butterfly bush, letting me snap a few photos before it wandered off. Now I’m reviewing my plans for the yard, trying to find a place to plant pawpaw

A Few Butterfly Answers

I ended yesterday’s post about Black Swallowtail Butterflies with a few questions:

I wonder if there is enough summer left for them? Will they emerge and mate this year? Or will they wait until spring, pausing the cycle as they sleep through winter’s dreary interlude?

Chrysalis August 26

This morning, the yard answered with uncharacteristic directness. There is definitely enough summer left — plenty of time for another generation of swallowtails.

Of all the remaining chrysalises, why should the one I photographed yesterday be the one to open today?

Butterfly August 27

Maybe because I had some time available today, for research? Why else would she allow me to photograph the strange fork at the end of her proboscis? I’ve noticed something similar before, but not on all of the butterflies. What’s going on here?

Butterfly August 27

This afternoon I learned that many species of butterflies emerge with their proboscises incompletely fused. After emerging, they mechanically connect the two halves, forming a tube. This has to be done fairly quickly, or the butterfly may end up with a permanently divided (and therefore non-functional) proboscis. In the above photo (taken only minutes after emergence), the process simply wasn’t complete.

The following enlargement, cropped from one of yesterday’s emergence photos, shows the groove that results when the two halves of the proboscis are properly connected. (The tip of this proboscis had a tiny fork remaining, evidence that the butterfly still had a bit of work to do.)

So much complexity, packed into so small a creature. Wonders and miracles in every detail.

More Swallowtails

Swallowtail August 5

The yard’s swallowtail cycle went into high gear through the early weeks of August. Which meant that, for a while, there were more caterpillars than the predators could eat. (And then the caterpillars ate faster than the parsley and fennel could grow, which meant another trip to the garden store.)

At one point there were so many caterpillars on the parsley, and so many eggs being laid, that mistakes were made.

Since I had a container ready, I decided to collect “a few more” caterpillars. (As it turned out, twenty-two was a few too many, forcing yet another trip to the garden store.)

Caterpillar August 20

I dreamed of waking one day to a container full of butterflies. An unlikely dream, yes, but a lovely one!

Butterfly August 20

(Unlikely because only three of my first thirteen caterpillars survived to become butterflies. Some died of unknown causes, some were destroyed when a predator broke into their enclosure, and three fell victim to what I suspect was a parasitoid.)

Chrysalis Damage Aug 19

I was thrilled when twenty-one of the twenty-two caterpillars survived to become chrysalises.

And, while the butterflies haven’t emerged in a coordinated swarm, they have begun to emerge. Twelve, so far, of the twenty-one. (Including two this morning.)

This is a vast improvement over three of thirteen!

Thrilled with this success, and having a bit of parsley left over, I’m still collecting caterpillars. Last weekend four of the latest group roamed until they were exhausted, then settled into chrysalises.
