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.

Collected by Ellison Orcutt, in Caroline County Virginia this small spring Andrena is a fan girl of mustards, particularly the spring mustards that are native and occur in wooded and semi-shaded areas in the spring, often very early in the spring.

Here is the male of the recently posted female Andrena arabis. The male illustrates what happens periodically with some of the males of this largely brown, dark group of mining bees which is that a few of them have a yellow, or in this case and off-white, clypeus. Surely this must be some sort of sexual signal as the females almost never have these markings.

A small bee, whose female is a gatherer of pollen from native mustard plants. However, this is the male as can be told by counting the number of antennal segments (13) and by the fact that it has a bright white clypeus. Which, with very very rare exceptions is something that only male Andrena have. This is Andrena arabis.

One of many small Andrenas out in the spring in Eastern North America. This one favors the pollen of brassicas. Photoshopping by Thistle Droege, photograph by Dejen Mengis.

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.

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.
