Fall’s Final Flutterings

Even in December, an assortment of butterflies graces the Texas landscape, taking advantage of our relative warmth and lingering nectar sources.

The Queen butterfly (Danaus gilippus) shown above can be distinguished from Monarchs and Viceroys by the white spots on its hindwings and darker color. I recently found a dozen of these beauties flocking around the remnants of Gregg’s mistflower (Conoclinium greggii ) in a Kerrville garden.

On the other hand, this Common Buckeye (Junonia coenia) found a congenial resting spot alongside the Willow City Loop in Gillespie County. Its family, the Nymphalidae, contains butterflies called ‘brushfooted,’ due to the reduced size of their front legs. Seventy-three species of this largest butterfly family are found in Texas, including fritillaries, checker spots, crescents, American Painted Ladies, and Red Admirals.

At the Lost Maples State Natural Area, I got my first look at a somewhat amusing butterfly known as the American Snout (Libytheana carinenta).There’s no question how its name arose. The pronounced elongation of its mouth parts look very much like a snout; they remind me of an anteater.

The Snout’s larvae, pupae, and adults are quite dull, resembling partially opened leaves. When adults rest on twigs with their wings folded and their antennae and snout aligned toward the twig, they often resemble a dead leaf.

Hackberry trees serve as hosts for the American Snout; adults feed on a wide variety of flowers, and often can be found sipping water and minerals from mud.

American Snouts do migrate, but not in a traditional north to south direction. Instead, they move locally among patches of suitable habitat, particularly after rains produce fresh hackberry leaves. A 1976 study discovered the butterflies moving in three different directions east of I-35, with one flight reversing directions between morning and afternoon. Their migrations are fascinating; this article provides more complete details.
