One of our smallest longhorn beetles, this species is brownish or dark grey with silky hairs on the wing cases, giving it a sheen. It has long antennae, where the 2nd segment is elongate – a feature which distinguishes it from the other two Grammoptera species found in Britain. All three have bulbous femora (top segment of the leg). Its front legs are orange and the antennae are banded with red and black.
Common on flowers especially Hawthorn and Hogweed and sometimes in well wooded areas.
Larvae feed on wood of dead twigs. Adults feed on nectar and pollen of flowers.
