Andrena nasonii. In this case a female, one of the least distinguishable species there is, but fortunately very common and so there are small and differences between the species and others that together allows us to recognize it when plowing through thousands of them.

An abundant Andrena, often found in lawns and disturbed field like situations. The males are as generic as they come but have a tiny point coming out of their integument on either side of the underside of their thorax. Thank goodness. Photographer ...

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.

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.

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.
