Tenthredo amoena

A black species richly marked with yellow and with a shiny, sparsley punctured head around the frons and inner orbits. Similar to Tenthredo distinguenda and Tenthredo thompsoni but in amoena the first antennal segment is entirely yellow and the tegulae are marked with yellow on the front margin. In the female this is the only Tenthredo species where the fifth tergite is yellow at the base and black at the apex.

Tenthredo amoena larvae feed on St John's-worts.
