Euura kirbyi

According to Taeger and Blank this species is conspecific with Pachynematus clitellatus and the description here is taken from Muche's description of Pachynematus kirbyi. The former Pachynematus species require further study and any descriptions are currently tenuous.

The pale colour is green in life fading to straw colour. The black markings are highly variable. Usually black are more or less the antennae, the ocellar spot, the back of the head, usually three stripes of the mesonotum, the scutellum, the mesosternum, the metapleurae, less often the mesepisternum and the top of the abdomen (horizontal stripes, at least on the basal tergite). The entire upper surface of the abdomen may also be black on the male. The legs are yellow with the base of the coxae, the bases of the femora, the tibiae and the tarsi more or less blackened.

Euura kirbyi larvae feed on sedges.

Size: 6.0 - 7.5mm.
