About Diadasia bituberculata (Cresson, 1879)
Diadasia bituberculata, commonly known as the bindweed turret bee and bindweed bee, is a species of chimney bee in the family Apidae. This species is found on the West Coast of North America and Mexico. Its range spans both Central America and North America, with a primary distribution along the West Coast of the United States, particularly in California. Colonies have been recorded as far north as Oregon and as far south as Baja California, Mexico. This bee species begins development as an egg, with typically 1 to 2 eggs laid per nest. After hatching into larvae, the individuals feed on pollen provided by their mothers until they reach adulthood. Once mature, they leave the nest to search for a mate. Adult bees are usually only active for a few months, between April and July. During this active period, the bees mate, build nests, gather food, and lay eggs. Towards the end of spring and into early summer, they seal off their nests. For the rest of the year, eggs hatch and larvae grow until they reach adulthood. The new adults exit their nests in early spring to start the cycle over again.
