Trichodes alvearius

Checkered bee beetle

Its larvae live inside bee and wasp nests preying on the grubs, while the harmless adults spend their time visiting flowers.

The bee-eating beetle is a densely hairy beetle with a black head and a metallic steel blue scutellum, and red elytra crossed by black bands; a black stripe runs along the inner edge of the wing cases, and the red tip is not reached by the last black band.

Larvae develop inside the nests of solitary bees and wasps, feeding on the grubs and stored food, while the adults visit flowers such as umbellifers and rarely take flight, relying on their bold warning colours for defence.
