Cymus melanocephalus
Family: Lygaeidae

The four bugs in this genus are distinctively shaped and have a highly punctured body and forewings. However, they can be difficult to separate.

C. melanocephalus lacks a pale central keel on the scutellum and the wings are punctured throughout.

This species is quite common in southern England in damp areas, hostplants including trefoils, loosestrifes and rushes.
