Megalopodidae

A small family in Britain, with three species in genus Zeugophora.  These are small beetles, either brown or black and orange-yellow in colour.  They are usually found feeding on the leaves of young poplars or aspens, where they cause characteristic damage, skeletonising the leaves by eating small round windows between the veins.  Larvae are leaf-miners, feeding in a black blotch between May and July.
