Pristiphora cincta - Species not placed in a group
More than one species may be concealed within Pristiphora cincta. Possibly a lowland species feeding on birch and a highland species feeding on bilberry. The female abdomen is red girdles on up to four middle tergites. Males often have a red girdle on the abdomen (lowland specimens?) but are best determined by examination of the penis valves.
Pristiphora cincta larvae feed on downy birch, willows, bilberry and bog bilberry.

Distribution: England, Scotland, Wales, Ireland
Flight period: April to June
Plant associations: Betula pubescens, Salix spp., Vaccinium myrtillus and Vaccinium uliginosum (downy birch, willows, bilberry and bog bilberry)
