The abdomen of a female Andrena nivalis. In that abdomen is a female stylopid which looks a bit like an odd head sticking out from underneath a tergite...she has been living in said A. nivalis for a long time...feeding on its innards...and, the stylopid has just given birth, (likely killing her in the process) to all her little babies. Nature: So cruel.

One of the relatively few fall Andrena bees (most occur on spring wildflowers). This dark species is associated with Goldenrods and Asters...but then again, that is the main nectar and pollen source of the Fall. They also have a tendency to show up in sandy areas and, indeed, this specimen is from the Carolina Sandhills collected by Heather Campbell.

Andrena species, Black-tipped Andrena, specimen collected by Jason Gibbs in OmanEvolution has blessed the genus Andrena with over 1500 different species, making it the second richest of all bee genera (Hairy-tongue Bees, Lasioglossum, are first).

A little male mining bee about the size of a grain of rice. Andrena personata is something I associate with sparse fields, not so much lawns. My guess that the usual lawn weeds don't have the right mix of patriotically native flower species it is looking for. Kind of pixie like, is what I want to say.

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.

This small Andrena is around fairly late in the season (May-June) compared to other Andrena and hangs on on woody low shrubs and brambles. Not common an prone to being misidentified as A. brevipalpis. Hannah Sutton did the pictures.

From George Washington's Birthplace comes a fall Frost Aster specialist. One of about 6 or so species that specialize on the pollen of Asters and sometimes Goldenrods, these species are uncommonly collected but likely more because people are not looking that true uncommoness.
