EUURA VICINA GROUP
Euura vicina - Proximal Dock Nematine
Nematus vicinus Serville, 1823
Nematus longispinis Kriechbaumer, 1885
North to northern Scotland, seemingly common and widespread (Musgrove, 2024).
In both genders the abdomen is entirely black. A similar species to Euura caeruleocarpa but the hind tibial inner spur is 1.5 times the length of the apical breadth of the hind tibia. In the male the spur is clearly more than half the length of the basitarsus. Both genders are mostly black with brown on the labrum. The legs are largely yellowish-brown. The cerci are shorter than the sawsheath when viewed from above.
Euura vicina larvae feed on birches, poplars, willows and broad-leaved dock.
Size: Female: 8.0 - 9.0mm, male: 7.5 - 8.0mm.
Status: Widespread, but infrequent
Distribution: England, Scotland, Wales, Ireland
Flight period: May to July
Plant associations: Betula spp., Populus spp., Salix spp. and Rumex obtusifolius (birches, poplars, willows and broad-leaved dock).
