Scientific Name:
Stygoparnus comalensis
Group:
Insects
Status/Date Listed as Endangered:
EN-US FWS: December 18, 1997
Area(s) Where Listed As Endangered:
Texas

The Comal Springs dryopid beetle was first discovered in 1987 and only recently described as a species in 1992. It is the only known subterranean aquatic member of the beetle family. Its eyes are non-functional and its skin is thin, translucent, and weakly pigmented. Adults reach only 0.12 inches long, and females are larger than males.

This species can only be found in the flowing and uncontaminated waters of the Comal and San Marcos Springs in Hays County, Texas. Although it is an aquatic insect, it does not swim, and diet probably consists of other aquatic invertebrates. It is believed that its primary habitat zone is permanently dark. Little is known about the reproductive behavior of this species.

This species is threatened due to its limited range, and a decrease in water quantity and quality and pollution due to human activities may threaten its survival. Conservation plans include monitoring of the species and its habitat, and the continued study of its biology and habitat needs.

Ten Creatures that may become extinct in the next 10 years

Leatherback sea turtles have been around since pre-historic times. And unfortunately, if the species is allowed to vanish, scientists believe it will foreshadow the extinction of a host of other marine species. It is estimated that there are less than 5,000 nesting female leatherback sea turtles in the Pacific Ocean today, down from 91,000 in 1980.
