Ramps. Allium tricoccum. Things in the onion group can be good pollen sources for bees. Ramps are no exception. Specimen and photo by Helen Lowe Metzman.

A pollinator of wild relatives of tomatoes, this species will alight upon and then vibrate tomato flowers using its wing muscles. These plants have cleverly hidden their pollen in tubular anthers that are primarily released when buzzed by bees at a certain frequency.

A couple of so so pictures of Andrena milwaukeensis. Check out the tiny dark hairs in the facial fovea.. Photo by Dejen Mengis

A bee (Andrena morrisonella) that may or may not be the same species as A. imitatrix.

Ugly Bee...For sure, but an interesting one. Brooke Goggins took this one on a grayish background to highlight the wings of this Andrena nasonii. This specimen was collected by Gabriel Karns as part of a study of rights of way in eastern Ohio. We noticed that it has some funny vein business going on.

Andrena nasonii. In this case a male, 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. Picture taken by Sierra Williams.

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 ...

From Acadia National Park in Maine, this is one of but a few Andrena that come out in the Fall.

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.

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.

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.

More from Yosemite National Park. Hmmm, that color, so blue, reminds me of famously blue bees such as Ceratina and Osmia...but, in this case, we are looking at Andrena chapmanae...one of the raree Andrena that are a strong metallic blue. I have to say that the combination of this midnight blue and deeply dark brown is very attractive.
