A somewhat odd position with its pollen covered (likely geranium pollen) leg out and its head cocked towards us. Photoshopping by Thistle Droege and photograph by Brooke Alexander.

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.

Most people don't realize how important willow trees are to our native bees in North America. They are a major pollen and nectar source early in the spring and they have more specialists than almost any other plant on the continent. Here is one of those specialists. This is Andrena nida. This bee feed it's young only the pollen from Willow.

Andrena spiraeana is one of the set of bees in the Andrena subgenus Trachandrena. One of the characteristics of this relatively distinctive group are the deeply impressed fovea between the compound eyes and the antennae. A spring bee, I associate this species with wooded wetlands...but I may be simply mistaken on that account.

Andrena uvulariae, Female, Recently, this species was known only from the type, but work by Mike Arduser, Joan Milam, and John Ascher have resulted locating additional specimens along the the male. It appears to be a pollen specialist on Bellflowers. This specimen is approximately 100 years old from the Smithsonian collection.

This is a first in what will be a series of pictures from Claire Kremen's Lab at U.C. Berkeley. This is Andrena vanduzeei, an endemic California bee, restricted to the High Sierras. Note the lovely blue metallic notes and surrounding dark hairs. Specimens collected in Yosemite National Park. Picture by Sydney Price.

An often uncommon spring Andrena, I associate with the Appalachians, this is a male with a sweet yellow clypeus. Collected by MaLisa Spring near Marietta, Ohio. Photograph by Brooke Alexander.

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.

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.

A larger Andrena...about the size of a honey bee. A spring forager, not well studied, but shows up here and there throughout much of the deciduous forest landscape of the East south of New England. Photo by Kamren Jefferson.

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.

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.

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.
