Description



Stenopterus rufus can reach a length of 7–16 millimetres (0.28–0.63 in). The body has a velvet-like hair. Elytra are very narrow. Antennae are about as long as the body and clearly segmented. The head and pronotum are black colored and the abdomen has a black background color horizontally crossed by yellow stripes. The first two segments of their antennae are black, the color of the following ones is variable but generally yellow with items III to V black at the apex, but sometimes items III to XI are entirely yellow or entirely black. Elytra are red with black base and apex. The legs are mainly red.

The adults can be encountered from May through August, completing their life cycle in two years. They are very common flower-visitors, especially Apiaceae species, Heracleum sphondylium and Ranunculus repens, feeding on pollen and the nectar.
