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.

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

Another uncommon woodland Andrena. Andrena thaspii also is largely unstudied. Kelly Graninger took the picture and Ellison Orcutt caught the bee in Virginia.

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.

Rare Bee Alert. Andrena uvulariae was described many years ago from specimens collected where I work in Beltsville, MD and then...it largely went off the radar screen as a legit species and all things that looked like this species were simply called A. ziziaformis.

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.
