Pristiphora rufipes - rufipes group
The species separations in the rufipes group are unclear. Only this Pristiphora species in Britain and Ireland feeds on columbine. The species are predominantly black bodied. Females of species in this group all have a distinct scopa on the apex of the sawsheath. Males and females of the rufipes group cannot be separated other than by food plant and DNA analysis at this time.
Pristiphora rufipes larvae feed on columbines. Eggs are laid into the margins of the leaves. Larvae feed from the leaf edge and there may be several feeding on a leaf, though they do not feed communally.
In captivity the larvae weave a dark cocoon between leaves or in the substrate and adults emerge after approximately two weeks.
Size: 4.5 - 5.5mm
