Melitta nigricans

Melitta is a genus of bees in the family Melittidae. It includes about 40 species restricted to Africa and the northern temperate zone. Most of the species are Palaearctic, though three rare species occur in North America.

They are bees of moderate size, generally 8 to 15 mm long. They are commonly oligolectic, with narrow host plant preferences. They resemble bees of the genus Andrena, though with radically different mouthparts and a scopa limited to the hind tibia and basitarsus.
