Overview
Hydaticus aruspex is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America and the Palearctic.
The Haruspex Predaceous Diving Beetle faces severe threats primarily from habitat destruction and water pollution in its limited freshwater environments. Agricultural runoff, urban development, and water extraction have degraded the quality of ponds and streams where this species depends for survival and reproduction.
