Male Andrena bees can be difficult to identify. Particularly complicated and confusing are the subgenus Melandrena. Here is a member of that subgenus....A. pruni. However!

A common spring western Andrena. More colorful than the average dark chocolate Andrena (fuscous is what the old timers would call it). Quite reddish in its integument in spots and a nice yellow clypeus as in this male. Collected in the fabulous Badlands National Park in South Dakota. Photo by Kelly Graninger.

Sexy Andrena. Yes, the normally black Andrena does have some sexy species. Here is one of my favorites. Andrena prunorum jacketed in amber with ribbing of white fur...or something like that. A common western species that leaked just enough out of the West to show up in Badlands National Park where we were studying the bee fauna of the Park.

A wee mining bee. Andrena robertsonii lives among the flowers, usually in mid to late spring, where it often lounges around gathering pollen on woody plants, things such as apples, roses, dogwoods, and sumacs. As most of you know it is super similar to A. brevipalpis, but I am not telling you anything new.

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.

Anthophora bomboides, a rather cosmopolitan Anthophora. Found throughout the north and down the mountain chains on both sides of the continent. I have my suspicions that western and eastern populations are possibly different species, but so far no one has talked to the bees' dna about that.

If you want a group of bees that generally present themselves well and look like bees not wasps choose the Digger Bee grouip. This male Anthophora californica was collected by Don Harvey in Hidalgo County, NM. Dryland area for sure and the distribution sits right in the dry areas of the West.

Anthophora curta....found in the drylands/deserts of western U.S. and Mexico. This is a rather small Anthophora and like many of the group, well groomed with small, short, mini=branched hairs. It seems to prefer composites and this particular one was found near the nowhere place of San Simone, Arizona at the eastern edge of its range. Collected by Don Harvey.

Another small Anthophora from the West Coast. This one is A. exigua and was collected in Yosemite National Park as part of ongoing studies of the fire ecology of that Park by the Claire Kremen Laboratory.

Now the back of the previous specimen, note the strong white/cream bands on the abdomen, one related group of Anthophora have these integument bands while the other species the integument is entirely black....tricky to photograph as it quickly burns the detail in the white.Note the tattered wings...this male was getting old...This bee was collected as part of a surv

Female, Anthophora plumipes, introduced into Maryland from Japan in the 1980s...and now common in the DC region. Likely to be split from A. plumipes back to an earlier synonym A. pilipes due to recent molecular work
