Description:

We had a group of bee nests on our site in the first part of last year. I have read that the solitary bee most likely to nest communally in this way is Andrena scotica (A. carantonica). I wonder if these pictures can confirm that identification.

You should be able to tell O.

You should be able to tell O. rufa with a glance at the head of the female, which has two horns sticking out from the front. All the Megachilines (Osmia and leaf-cutters) carry their pollen on combs under the gaster, and are a lot chunkier than Andrena, which all carry pollen on the legs. Lots of solitary bees in different genera nest in large aggregations in soil (though as Matt says, these are not actually nesting there).

Thank you. I wouldn't have guessed that. Very interesting.
