Trichius gallicus

French flower chafer

This flower chafer's orange-red hairs and incomplete black bands help distinguish it from its close relative, the bee beetle, while both mimic bees on flowers.

Size10 to 12 mm body length
WhenMay to August

The French flower chafer has a black head and pronotum, with yellowish wing cases crossed by a few incomplete black bands, and its body is covered in orange-red hairs that give it a bee-like appearance. The first black band on each wing case does not reach the scutellum, a useful identification feature.

Adults visit a wide range of flowers from late spring through summer, feeding on pollen and petals while mimicking the appearance of bees. Only males show a narrow band of white hairs near the tip of the abdomen.
