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?) but are best determined by examination of the penis valves.

Larvae feed on downy birch, willows, bilberry and bog bilberry.
