Ancylandrena
Ancylandrena is a genus of mining bees in the family Andrenidae, established by Cockerell in 1930. The genus contains five described species, all found in North America. One species, Ancylandrena larreae, is commonly known as the creosote bush ancylandrena due to its association with Larrea tridentata. These are solitary bees that nest in the ground.
