Dolerus brevicornis

Dolerus brevicornis only recently separated from Dolerus asper as a species in Britain. Males can be determined by the penis valve shape and the phenology. In females, the setae on dorsolateral edge of pronotum are distinctly shorter than the diameter of an ocellus and the clypeus is more or less symmetrical with the emargination approximately one third as deep as its median length. See Heidemaa et al for key.

Larvae feed on sedges and grasses.
