Diadasia bituberculata
In 3 days ~10%
Diadasia bituberculata, also known as bindweed turret bee, and bindweed bee is a species of chimney bee in the family Apidae. The bindweed turret bee is found on the West Coast of Mexico and North America. The bindweed turret bee's range extends through both Central and North America, but it is found primarily on the West Coast of the United States, especially in California. Colonies have been found as far North as Oregon and as far south as Baja California, Mexico.
This bee species starts out as an egg, usually laid 1-2 to a nest. After hatching into larva, they feed upon pollen provided by their mothers until they reach the adult stage. At this time, they will leave the nest in search of a mate. Adult bees are typically active for only a few months, between April and July. During this period the bees will mate, build their nests, gather food and lay eggs. Towards the end of spring and into early summer, they seal off their nests. For the remaining months of the year, the bee eggs will hatch and the larva will grow until they reach the adult stage and exit their nests in early spring, starting the cycle again.

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bindweed Turret Bee in San Diego on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Bindweed Turret Bee is recorded against all the insects logged in San Diego (9 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
