Euura abnormis

Probably confined to the Cairngorm Plateau near the summit of Braeriach.

The female is a dull insect with heavy coriaceous sculpture all over and with wings that do not reach the apex of the abdomen. Predominantly black with a yellow head and mesonotum. Males can be identified by the heavy coriaceous sculpture on the head and thorax, small eyes and the shape of the penis valve.

The species is a high montane species of the arctic-alpine zone. Larvae are thought to feed on willows and probably dwarf willow.
