Regionally common to sometimes even abundant, this is one of the larger Andrena of the spring. It can occur in almost any habitat, gathering pollen from a wide variety of the hugely abundant pollen and nectar sources that occur in Woodlands and surrounding scrub lands.

Andrena barbara, female

A rather pollen riddled specimen, this uncommon (at least in Maryland) species is uniquely outfit with a long-strap like labral process...for those of you who are technically inclined.

For some reason I really like the lighting on the face of this specimen... eerie, the bee contemplating the decline of its own kind, that sort of thing. But I depart...Here is Andrena bradleyi, the Long-faced Mining Bee, a vaccinium (blueberry) specialist. If you hang out around blueberries then you might find this bee...the flowering plants that is.

As its name implies, Andrena caerulae, is a bee with a deep blue shimmer to its skin. Unlike the plain black models of most of the other 500+ species of Andrena this species stands out, making identification a bit easier.

The red maple, Acer rubrum, often one of the most dominant trees in deciduous woods in the East. It blooms very early in the spring and provides pollen and nectar to the set of bees, and flower flies, that come out early.

Ohio Buckeye. Aesculus glabra. Nice open understory tree you see more towards the west in Maryland and the Eastern U.S. Attracts a variety of woodland loving bees...in particular Augochlora pura. A nice color match. Picture and specimen by Helen Lowe Metzman.

Pennington County, South Dakota, Badlands National Park

A large bright green with blue overtones Agapostemon from Badlands National Park. One of several species present there and very similar to A. virescens and a bit tricky to tell apart. Photo by Wayne Boo with help from Ben Smith on upping the Photoshopping techniques.

Male Agapostemon's almost all have this same pattern, Metallicy green on the head and thorax and then striped yellow and black on the abdomen. Females uniformly don't have yellow anywhere. Why is good question as this male yellowness syndrome runs throughout the bee kingdom, cutting across families.

Maine, Collected by Sara Bushman

A specialist on early spring blooming brassicas. This one was collected just a few days ago along a very urbanized and disturbed section of Indian Creek in Beltsville, Maryland. Other than an overstory of trees all the herbaceous material growing seem to be invasive plants.

A couple of shots of Andrena asteris. Turns out the species is, indeed, an aster specialist. Not particularly common, unless you spend a lot of time looking at asters. If you spend a lot of time looking at willows then good luck finding this species Kiddo. Photo by Wayne Boo.

One of the relatively few fall Andrena species, this one from West Virginia. As the name implies, it is a lover of asters, and probably only uses Aster pollen to feed its young. Photograph by Brooke Alexander.
