Rest Stop

Not far from the spot where I discovered salt marsh morning glories abloom, this dragonfly paused at the edge of a water-filled ditch while dozens more of its species continued to buzz over the water.

I’ve tentatively identified it as a black setwing (Dythemis nigrescens), a dragonfly native to Texas, New Mexico, Arizona, and parts of Mexico. Sometimes confused with the slaty skimmer (Libellula incesta), the black setwing is smaller, with a more slender abdomen.

According to Odonata Central, these setwings enjoy perching atop twigs near the water, generally in open areas. That fits the behavior of this dragonfly, except that it hadn’t chosen a twig for its perch. This expanded view shows its resting spot for what it is: the four-inch long seed pod of a slim milkweed plant (Asclepias linearis).

Though obscured in the photo above, the delicate flowers of this milkweed are eye-catching: perhaps to the eyes of a dragonfly, the pods are equally attractive, and even more useful.

Some Friends for the Big Green Guy

The Big Green Guy ~ photo by Steven Schwartzman

This little marvel munching away on a gaura leaf, clearly unwilling to interrupt his meal in order to tidy up for the camera, has been tentatively identified as the larva of a white-lined sphinx moth (Hyles lineata): the same moth I featured recently on The Task at Hand.

The first time I saw the creature, I dissolved into giggles and immediately dubbed him the Big Green Guy. His vulnerable chubbiness, his tiny, multi-purpose feet, his air of concentration, his apparent lack of embarassment at being revealed as a messy eater: all evoked a response of absurd protectiveness.

Unable to help myself, I emailed his image to friends. Despite mixed reviews, everyone recognized it as a caterpillar, although some less sensitive souls deemed it ‘just’ a caterpillar. “Yes,” I said. “It is a caterpillar. But it’s not just any caterpillar. It’s an Alice in Wonderland, ‘Let me look you in the eye and ask you some questions’ caterpillar.”

Eventually, I purchased and hung a print of the creature on my wall. A neighbor said, “You might as well have mounted a collection of cockroaches.” I considered her judgment unnecessarily harsh, and said so. “To each her own,” she said.

Over the months, I began to wonder why I never had found a caterpillar. I saw monarchs being raised here and there, and occasionally a friend would find a chrysalis hanging from a lawn chair or a shrub, but caterpillars of any sort evaded me.

Then, in late October of this year, I noticed yellow tape along a roadside, attached somewhat casually to stakes. Suspecting that someone might have marked a milkweed patch, I stopped to explore. When I did, I not only found milkweed plants, I found a group of monarch larvae happily feeding: as plump and adorable as the Big Green Guy.

This one appeared to be sampling a stem.

A second was making short work of what seemed to be an especially tasty plant. At the time, I didn’t notice what appears to be an empty chrysalis nearby.

Focused on eating as much milkweed as they could, as quickly as possible, the group clearly wasn’t interested in posing, but they provided a wonderful hour’s entertainment.

In a recent post on his Learn Fun Facts blog, Edmark M. Law offered this quotation from Charles Dickens’s 1850 novel, David Copperfield:

Indifference to all the actions and passions of mankind was not supposed to be such a distinguished quality at that time, I think.
Yet I have known it very fashionable indeed. I have seen it displayed with such success that I have encountered some fine ladies and gentlemen who might as well have been born caterpillars.

Dickens might have sought a different analogy, had he met the Big Green Guy and his friends.

Spring, On The Wing

A Halloween pennant dragonfly (Celithemis eponina) clasps the tip of a plant known as rattlesnake master (Eryngium yuccifolium) on the Nash prairie

 

Today I saw the dragon-fly
Come from the wells where he did lie.
An inner impulse rent the veil
Of his old husk: from head to tail
Came out clear plates of sapphire mail.
He dried his wings: like gauze they grew;
Thro’ crofts and pastures wet with dew
A living flash of light he flew.
                                “The Dragon-Fly” ~ Alfred Lord Tennyson (1833)
