A bee that feeds its babies a restricted diet. In this case that diet is that of Geranium pollen. While I didn't check this specimen from Virginia those lovely pollen grains on its hind legs are very likely Geranium.

Cast skin, Prince George's County Maryland, collected by Richard Orr

We have shots of both the male and the female of this Paraguayan species. The group occurs from the deserts of North America down into southern South America, the males have bulbous and rounded hind femurs, modifications seen in a number of bees species around the world.

Tim McMahon hunted down this Ancyloscelis in Costa Rica. The long tongue on this relatively small bee is a thing. This group as a whole has an affinity for flowers with long carollas. In particular, the love morning glories. Which is interesting, because you don't really see morning glories in the seed mix for pollinator plots.

Andrena aliciae, male

A specialist on early spring blooming brassicas. This one was collected just a few days ago along a very urbanized and disturbed section of Indian Creek in Beltsville, Maryland. Other than an overstory of trees all the herbaceous material growing seem to be invasive plants.

Collected by Ellison Orcutt, in Caroline County Virginia this small spring Andrena is a fan girl of mustards, particularly the spring mustards that are native and occur in wooded and semi-shaded areas in the spring, often very early in the spring.

One of the relatively few fall Andrena species, this one from West Virginia. As the name implies, it is a lover of asters, and probably only uses Aster pollen to feed its young. Photograph by Brooke Alexander.

A couple of shots of Andrena asteris. Turns out the species is, indeed, an aster specialist. Not particularly common, unless you spend a lot of time looking at asters. If you spend a lot of time looking at willows then good luck finding this species Kiddo. Photo by Wayne Boo.

A very early spring bee, covered in pollen, collected by a homeowner in Bowie, Maryland

From the Great Smoky Mountains of Tennessee comes Andrena fenningeri, one of the very early spring bees, often associated with red maple bloom. In this case a male. Amber Reese took the picture and Elizabeth Garcia did the shopping.

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.

An odd, dark Andrena bee of deep sandy areas that comes out in the middle of summer

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.

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.

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.
