Monophadnoides rubi

Recorded widely much of mainland Britain (Musgrove, 2023).

The thorax is entirely black and the abdomen almost so. Hind tibia black but on the outer side of the base it may be dark rather than black. The head has deep supra-antennal grooves. The antennal pedicel is as broad as, or broader than, it is long. Tarsal claws have a basal lobe and are bifid with the inner and outer tooth close together.

Monophadnoides rubi larvae have branched spines and feed on meadowsweet, avens and bramble species.
