Wasp beetle

Description:

Clytus arietis, the wasp beetle, is a wasp-mimicking longhorn beetle species in the genus Clytus. It reaches 9–18 millimetres (0.35–0.71 in) in length, and flies well in sunshine from May to July, often visiting flowers for pollen and nectar. It is harmless but is protected by its wasp-like colours and movements, making it a Batesian mimic. The larvae live in dead wood. It also emanates a wasp buzz-like noise when threatened. They can be seen wandering around on flowers from late spring to early summer, and they are easily mistaken for wasps.
