Andrena anisochlora
Miner's Lettuce Miner
Andrena anisochlora is a solitary mining bee in the family Andrenidae, first described by Cockerell in 1936. Like other Andrena species, it is a ground-nesting bee that excavates tunnels in soil to create nest cells provisioned with pollen for its larvae. The common name "Miner's Lettuce Miner" suggests a likely association with Claytonia perfoliata (miner's lettuce) as a pollen or nectar source. It is part of the diverse Andrena genus, which contains over 1,500 species worldwide and represents one of the most speciose bee genera in North America.
