Batrisodes venyivi
Helotes Mold Beetle
Batrisodes venyivi, commonly known as the Helotes Mold Beetle, is a small, eyeless troglobitic beetle in the family Staphylinidae. It is endemic to eight caves in Bexar County, Texas, and was listed as endangered under the U.S. Endangered Species Act in 2000. The species exhibits classic cave-adapted traits including elongated antennae, legs, and sensory setae. Very little is known about its behavior, population trends, or life history due to the logistical challenges of accessing its subterranean habitat.
