Osmia sp.

Bees in the genus Osmia are commonly called mason bees. They earn this name from the “masonry” or mud material that they use to build their nest. Osmia bees are all solitary, meaning that there are no workers and each female is fertile and creates her own nest. There are more than 300 Osmia species in the Northern Hemisphere.
