Bees in Bunkers

From the Common Questions page of this blog:

WHY ARE THERE SO MANY BEES IN THE BUNKERS?


There are many common species of solitary bees that nest in the ground. Solitary bees construct individual nest tubes, each with its own opening.


They often nest in large congregations with many nesting holes arranged very closely together.

Ground nesting bees generally prefer nesting in areas with morning sun exposure and well drained soils containing little organic matter ... like bunker faces. Tunnels are excavated in areas of bare ground or sparse vegetation and damp soils are avoided.


Solitary bees rarely sting.
