Cymus claviculus
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.

This species is recognised by the absence of a dark mark on the cubital vein of the forewing (
see C. glandicolor) combined with a largely pale head. The critical feature involves a line of punctures near the corial-claval suture, followed by a narrow impunctate band (below right), although this feature is not always clear.

Often found in drier habitats than the others, on sandy heaths and dry meadows, where associated plants include knot-grass and toad rush.


Compare: C. glandicolor, C. melanocephalus
