  Bindweed Turret Bee, Bindweed Bee, Digger Bee, Chimney Bee

  Diadasia bituberculata is a solitary ground-nesting bee in the family Apidae, commonly known as the bindweed turret bee. It is native to the western coast of North America, with its range extending from Oregon through California to Baja California, Mexico. The species is an obligate specialist pollinator of bindweed (morning glory), foraging almost exclusively on plants in the genus Convolvulus. Females construct distinctive soil turrets at nest entrances in flat, bare ground, provisioning underground cells with pollen for their offspring.
