Tenthredo notha Klug, 1817

Tenthredo notha

One of a complex of four species: arcuata, brevicornis, notha, schaefferi. Males of the four species cannot always be reliably separated, though Taeger has produced a key to males on the continent. Females of Tenthredo notha can be separated by the shape of the hypopygium and the hind tibia being marked with black apically. The broad yellow band on tergite one does not narrow at the lateral edges.
Larvae feed on clovers and vetches.

Size: approx. 9 - 11mm

Status: Widespread

Distribution: England, Scotland, Wales, Ireland

Flight period: July to August

Plant associations: Trifolium repens (white clover) and Vicia cracca (tufted vetch)
