Pristiphora luteipes - Pristiphora ruficornis group
Males are unknown. This species cannot always be distinguished from Pristophora aphantoneura. The surface sculpture of the mesepisternum is not a reliable character. Separation of the two species is best achieved by detailed examination of the saw, though small differences in the hypopygium may also be diagnostic.
Larvae feed on white willow, eared willow, creeping willow, tea-leaved willow, osier and purple willow.
Size: 3.9 - 5.2mm
Status: Data deficient
Distribution: England, Scotland, Wales, Ireland
Flight period: May to Aug
Plant associations: Salix alba, Salix aurita, Salix repens, Salix phylicifolia, Salix viminalis and Salix purpurea (white willow, eared willow, creeping willow, tea-leaved willow, osier and purple willow)
