Monophadnoides ruficruris

Recorded widely in England and Wales, mostly south of the Wash but with some records from northern England. Benson (1952) noted the range as extending north to Lanarkshire although there are no recent Scottish records (Musgrove, 2023).

The thorax is black and the abdomen almost so, but the pronotal margin and tegulae are yellow. The hind tibia are yellow. The head with the supra-antennal grooves faint or absent. Tarsal claws are bifid with the inner and outer tooth well apart.

Monophadnoides ruficruris larvae have branched spines and feed on brambles, etc.
