Mason Bees - Osmia

Group Description

Solitary bees which excavate tunnels or use already existing ones to lay their eggs into. They line mud in the tunnels before adding pollen then the egg then mud again. They repeat until the tunnel is full. The end result is a series of cells. Females are always layed first at the back with the most protection from predators as they are the most important.
