Dolerus schmidti

A black bodied insect. Both sexes have entirely red hind femora with tibiae that are almost, or entirely, black. In the similar Dolerus gonager and puncticollis, the red occurs towards the apex of the femora and part of the tibia. Puncturation of the thorax and the sawsheath are very similar to D. puncticollis. This species cannot easily be distinguished from Dolerus liogaster with which it was previously confused. Phenology and genitalia are determining factors.

Associated with woodland. Larvae feed on grasses.
