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.

Ah, Andrena vicina one of several Andrena or mining bees that feed their babies almost entirely the pollen of blueberries. This large, honey bee sized Andrena is noteworthy for the dark pollen carrying hairs on its legs.

Various Andrena, adding to the catalog....most with bad hair. Sigh.

Andrena virginiana, female

Andrena wellesleyana is one of the many Andrena species. It is also one of a number of species where the males have extensive yellow on their faces while the females are completely black. I the bulk of species both males and females have black faces.

This is a bee I don't see that often. It is both northern and Appalachian, but even in those areas it seems to be not terribly common. It looks fairly similar to its cousin Andrena nasonii, but Andrena wheeleri. Is a bee that forages on low herbaceous vegetation mostly. Just another connector in the largely undocumented web of bees and plants. .

Andrena wheeleri - closely related to A. nasonii. Not very common, northern and Appalachian. Would be nice to know more about its role in the world. Photograph by Erick Hernandez. Bee collected by Ellison Orcutt in his studies of the bees of Virginia.

Andrena, which seem more prone to such things, perhaps because they are just a touch more delicate. So, it is nice to see a beautiful specimen like this Andrena wilmattae from Badlands National Park. A lovely presentation and our photographer, Anders Croft did a lovely job laying this specimen out. A joint venture I would say.

A small spring Andrena, the female uses pollen from Zizia plants to provision her nest. This specimen was captured by Nancy Adamson in the mountains of West Virginia.
