Burrowing bees, genus Andrena
These burrowing bees, in the genus Andrena, were apparently overwintering in a home in Valley Springs, California. The customer called, and gave us a baggie with 10 of the burrowing bees. The specimens were collected approximately March 3, 2016 and given to our technician, Jason Price.
The bees were showing up in the bottom track of an upstairs window, every time the sun hit the window. The window faces south-east.
Burrowing bees get their name from burrowing in the ground.
