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.

Andrena asteroides, a late season aster specialist (thus the name). This species along with a number of other Andrena specialize on this group of plants, the rest of the Genus Andrena are primarily spring flower specialists. Note the very dense pollen carrying hairs on the hind femur. Wayne Boo took this picture.

Andrena atlantica. One of over 100 Andrena species in the Mid-Atlantic area. The male of this species does not have a positive means of being identified from A. alleghaniensis. Some needs to figure this out along with many other things. Photo by Sydney Price.

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.

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.
