what is your thinking on willows? Like most people, maybe not much. They make great wicker baskets. They also tolerate some pretty extreme conditions along rivers, streams, tundra, that other trees can handle. In the East they are the largest plant being that has "specialist" bees.

Andrena macra. One of almost 100 species of Andrena that occur in the State of Maryland.

Andrena macra, a southern bee that just barely makes its way to Maryland. Seems to like to aggregate nests in sandy areas and create small colonies, although colonies are probably a poor word choice, perhaps more likely they just like to nest near one another.

A little tiny Andrena bee collected in the sandhills of North Carolina by Heather Campbell. Not much is know about this species, other than it appears to be uncommon and spotty in occurrence and runs from the West to the East coast with a fair amount of variation, which usually indicates that other species may be hidden within this one. So much work to do.

Another dark northern Andrena. This one also runs down the high elevations of the Rockies and the Appalachians. Collected in Hancock County, Maine and contibuted by Alison Dibble.

A bee (Andrena morrisonella) that may or may not be the same species as A. imitatrix.

From Anne Arundel County, in Maryland, this is one of but a few Andrena that come out in the Fall.

What a lovely female Anthidium manicatum from Massachusetts. This species is a non-native species that has successfully invaded much of the Eastern parts of North America, in particular it is fond of ornamental gardens containing furry leaved plants which it uses to line its nest.

Anthidium manicatum is an invasive bee that showed up sometime in the 19 eighties in North America. It is particularly fond of garden plants such as stachys and appears to largely be restricted to areas of human occupancy. The specimens come from Massachusetts, and I wish I could recall who gave them to me, but for now I have forgotten.

A gynandromorph is a bee that exhibits characteristics of both sexes. In the other two species (Lasioglossum and Bombus) the split was bilateral..one side male and the other, female. In this Anthidium oblongatum (an introduced species) almost the entire bee is female with the apparent exception of having a seventh abdominal segment and genitalia.

An odd and rare record of an Anthidium that normally occurs far to west in the dry part of the northern Great Plains, in this case it showed up on Isle Royale National Park where other northern prairie species also reside.

Various Andrena, adding to the catalog....most with bad hair. Sigh.

Andrena wellesleyana is one of the many Andrena species. It is also one of a number of species where the males have extensive yellow on their faces while the females are completely black. I the bulk of species both males and females have black faces.

Of the woodland oriented bees this is regionally the most common one, Andrena carlni, this male is relatively easy to tell because of the black hairs that line the edges of the eyes and the ocelli that are set back from the back of the head. Photography by Amanda Robinson.
