Narrow-Footed Hygrotus Diving Beetle (IMAGE) University of Wyoming Caption This rare aquatic beetle, known as the narrow-footed Hygrotus diving beetle and native to only central Wyoming, may be in need of some federal protection. Lusha Tronstad, lead invertebrate zoologist with the Wyoming Natural Diversity Database at UW, has been studying the beetles since 2010. Her research is in a paper, titled 'Using Species Distribution Models to Guide Field Surveys for an Apparently Rare Aquatic Beetle,' that was published June 4 (today) in the online version of the Journal of Fish and Wildlife Management.
