It is found on Hogweed (hence its specific name) and is a pest of celery and parsnips, where it damages the vegetables by leaf mining. The species is dimorphic in that its body can be either black or else orange-brown.
The males display on the upper surfaces of leaves on sunny days during May. Mating takes place when a female arrives (pictured). In Britain, the species is distributed widely across southern and central England; in Wales records are mainly near the coast.
