Megalonotus emarginatus
Family: Lygaeidae

Megalonotus species are medium-sized ground bugs in which the pronotum is all dark and coarsely punctured, particularly across the posterior. The front femora bear a large tooth and several smaller ones.

In  M. emarginatus the pronotum is covered in long erect hairs but the hind corners are protruberant and sharply-angled backwards (the hind margin of the pronotum is gently curved in the very similar M. chiragra.) 

Locally common across southern Britain in a variety of dry habitats.

Adult: All year
Length 4.5-5.5 mm
