Dolerus bimaculatus

The abdomen is girdled with red in both sexes and in females the tegulae are red (at least edged with red tint in males). The scutellum is very densely, irregularly and coarsely punctured all over with the coarsest much larger than those in the middle of the lateral lobes of the mesonotum.

Dolerus bimaculatus larvae feed on horsetails in wet habitats.
