Dolerus picipes - Tar-foot Griever

Recorded widely across most of mainland Britain (Musgrove, 2023).

An entirely black species. In females, the sawsheath is very broad at the tip (as wide as the apical width of the hind tibia) with long curved setae. In both sexes there is a shiny unpunctured area adjacent to the sulci posterior to the ocelli. Males can be determined by the penis valve.

Dolerus picipes larvae feed on grasses.
