Euaesthetus similis Casey, 1884

Note.

See Puthz (2014) for identification and illustrations. The available collection data (Puthz 2014) indicate that this species is predominantly found near water, inhabiting wetlands and areas along rivers. One specimen was collected in a muskrat nest. Less often, the species has also been collected in drier microhabitats including an alvar and cotton fields, although both of these habitats may experience flooding during heavy rains. Males can be easily recognized among other Euaesthetus by their strongly iridescent elytra and bifurcate parameres of the aedeagus (Puthz 2014).
