These beetles inhabit sunny forest edges, mixed coniferous forests, spruce pine forests and alpine and mountain pastures.
Description
S. melanura in copula
Stenurella melanura can reach a length of 6–10 millimetres (0.24–0.39 in).[3] This beetle has a very narrow and rather long body. The antennae are about as long as the body. The head, pronotum and abdomen are black. The elytra are yellow-brown in males, with a black colored tip. In the females the elytra are reddish. The elytral suture is often black-colored, especially in the females, while the slender males have a darker tip and the black drawing is somewhat less pronounced.
Biology
Both females and males can mate several times, and the males often remain on the female to prevent her from interacting with other males. Larvae develop in rotten wood of deciduous and coniferous trees, especially Castanea sativa.[3] Adults can be encountered from May through September,[3] completing their life cycle in two years.[3] They are very common flower-visitors, especially Apiaceae species, feeding on pollen and the nectar.
