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.

Sunflowers. Specifically, the genus Helianthus to separate out the other "sunflower" plants. Only found in North America. So tall and glorious that we have adopted many for our gardens. Thrusting skyward they telegraph their supply of pollen and nectar to the bees that only feed their young pollen of Sunflower. Here is one of them. The appropriately named A.

Another uncommon Andrena bee in the subgenus Trachandrena, this one seems to favor wooded areas. Formerly little known in the state, it is now recorded in 11 counties. Photography by Hannah Sutton.

Andrena hippotes is another Andrena in the Tracandrena subgenus. It does have the distinctive feature, at least in the East, of having orange legs, which helped separated out from the other Tracandrena species. However, like many of these colorations and markings in bees, it is likely to sometimes not be there.

Go to the woods in the Eastern United States, find a blooming Rhododendron, look for this bee, it specializes Rhodos and Azalea pollen for its babies. Collected in Giles County (probably on a Rhododendron) by Barbara Abraham's students at Mountain Lake Biological Station.

Andrena cragini, male, new species record for South Dakota from Badlands National Park as part of a park wide inventory, this small Andrena species appears to be a Leadplant pollen specialist, Joyce, Colby, and Amber

Another photograph of the very common Andrena cressonii, captured right here in Prince George's County, and photographed by Erick Hernandez.

Andrena cressonii - Common, shows up almost everywhere in the spring. Secret identification tip of the day: There is a raised line slanting across the pronotal collar that is usually visible from one side of there other (depending on how the head is cocked). As you go west the legs tend to get very orange...is it a different species?

Andrena dunningi. A large dark Andrena. This lovely female, in fresh plumage, is relatively easy to identify simply by the orange brown color of its body hairs along with the nearly black hairs located on its hind legs which it uses to carry pollen to its nest.

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

Here is the male of the recently posted female Andrena arabis. The male illustrates what happens periodically with some of the males of this largely brown, dark group of mining bees which is that a few of them have a yellow, or in this case and off-white, clypeus. Surely this must be some sort of sexual signal as the females almost never have these markings.

A couple more shots of Andrena asteris, one male, and one female. Note the super fluffy hairs on the hind tibia of the female.
