FWS Digital Media Library — Rhadine exilis The U.S. Fish and Wildlife Service’s National Digital Library is a searchable collection of selected images, historical artifacts, audio clips, publications, and video. The genus Rhadine as a whole is very widespread. They live in moist and cool environments. An indicator of evolutionary history, it is typically found in southwestern Texas. Several species are only found in mountaintops while others are restricted to deep caves or more general subterranean habitats. However, no food habits are known in any species of the genus Rhadine but the family of carabids are typically predaceous. Carabid beetle species diversity, community composition, and wing-state act as ecological indicators of forest age. The genus therefore, is an appealing group for studying regressive evolution (the reduction or total loss of traits over time) and biogeography. Also found mainly in North America.
