Tête-à-Tête

Two Gray Hairstreaks sipping nectar from antelope horn milkweed (Asclepias asperula)

One of the most common butterflies on the North American continent, the Gray Hairstreak (Strymon melinus) also ranges into Central and northern South America.

In their book Butterflies of Houston and Southeast Texas, John and Gloria Tveten describe hairstreaks as “fast-flying butterflies that dart about so quickly and erratically that they are extremely difficult to follow.”  I’ve certainly been frustrated by that behavior, but this pair, intent on sips of nectar, were more than willing to tolerate my presence.

Found on a milkweed-covered  hillside along the west prong of the Medina River, very near The Nature Conservancy’s Love Creek Preserve, these hairstreaks were accompanied by Buckeye, Sulphur, and American Painted Lady butterflies: all enjoying the abundance of late spring flowers, and perfect flying conditions.

What a Difference a Week Makes

Fewflower milkweed, April 26

Nestled among the ferns lining the boardwalk at the Watson Rare Native Plant Preserve, this pretty orange milkweed fairly glowed. Initially, its color tempted me to think I’d found butterfly milkweed (Asclepias tuberosa), but the purplish cast to the flower’s center, the single stem, and thin leaves suggested otherwise.

In fact, I’d come across fewflower milkweed, Asclepias lanceolata. A species native to coastal plains of the United States from New Jersey to Florida to southeastern Texas, its bright, reddish-orange flowers frequently appear in marshes, or wet pine barrens characterized by well-draining sandy or loamy soil. A host plant for monarch, queen, and soldier butterfly larvae, A. lanceolata also provides nectar for adult butterflies and insects.

Tall, with lance-shaped leaves opposite one another on the stem, the plant  branches near the top into one to three umbels.  Each contains an average of only seven flowers, giving the milkweed its common name: fewflower. When I returned to the preserve a week after finding the plant with partially opened flowers, nearly all in its three umbels had opened, making its few flowers very impressive, indeed.

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.
