Andrena impolita
Unpolished Mining Bee, unpolished miner
Andrena impolita is a solitary mining bee in the family Andrenidae, described by LaBerge in 1987. The species is known from Central America and North America. Like other members of the genus Andrena, it is a ground-nesting bee that excavates tunnels in soil to create nest cells provisioned with pollen for its larvae. The common name "unpolished miner" refers to the relatively dull or unpolished appearance of the integument compared to some related species.
