Tenthredo brevicornis
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. Tenthredo arcuata and brevicornis females can be distinguished by the shape of the saw teeth.
Larvae of the four species probably all feed on clovers but larvae of brevicornis are unknown.
Size: approx. 9 - 11mm
Status: Common
Distribution: England, Scotland, Wales, Ireland
Flight period: Uni- or bivoltine, June to September
Plant associations: Probably Trifolium repens (probably white clover and other clovers/trefoils)
