Another member of the difficult to identify Trachandrena subgenus of Andrena. I think that I have the females sorted out (more or less) but the males...oi! This specimen from Maryland. Picture by Amanda Robinson.

There are a group of bees in the genus Andrena that form a fairly distinct subgenus called Tracandrena. They are notorious for being difficult to separate out and, in particular, the males all look pretty much the same. I have created a little Excel spreadsheet that help separate out the females, if anyone is interested.

Two different specimens of Andrena geranii. A northernish species that appears to be a specialist on ....geraniums. Notable is the slight blue metallic sheen to the body. Aaman Dengis and Brooke Alexander took the pictures.

Another odd ball Andrena from the Channel Islands. This one is A. gnaphalli, collected as part of a larger study of bees in climatically vulnerable National Parks. An apparent Asteraceaea specialist with some glints of green and red instead of the normal black integument.

Not the best lighting, but this is Andrena gnaphalii....a interesting Andrena with a green tinge. From the Channel Islands off the coast of California. Photo by Anders Croft.
