This was a good year for tickle bees at Buhr. These bees nest in the ground, in the upper basin behind the swimming pool. We call them tickle bees because they are harmless to humans. The ones we see on sunny days in April are males, cruising at about 12 inches above the ground, looking for partners.Fun fact: male bees have no stingers.
Here's some info from a school in Oregon:
Our tickle bees are probably in the genus, Colletes.They are also called, "cellophane bees" since they line their nests with a cellophane-like substance.
