Another uncommon Andrena bee in the subgenus Trachandrena, this one seems to favor wooded areas. Formerly little known in the state, it is now recorded in 11 counties. Photography by Hannah Sutton.

Andrena hippotes is another Andrena in the Tracandrena subgenus. It does have the distinctive feature, at least in the East, of having orange legs, which helped separated out from the other Tracandrena species. However, like many of these colorations and markings in bees, it is likely to sometimes not be there.

Yellow Bee: Yellow Pollen : Andrena hirticincta : Maine : Agriculture field edges. This is a fall bee, a bee of goldenrod and aster. How nice. Collected By Brianne Du Clos and photographed by Dejen Mengis.

Andrena ilicis. A bit of a mystery bee. It seems to be associated with Woodlands, but other than that I don't have much of a feel for the species. This one was collected in Somerset County Maryland.

From malaise traps set in the woodland bottomlands of the Patuxent River comes the uncommonly detected Andrena illicis. Here is a male with its notable orangish legs.

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.

Andrena, which seem more prone to such things, perhaps because they are just a touch more delicate. So, it is nice to see a beautiful specimen like this Andrena wilmattae from Badlands National Park. A lovely presentation and our photographer, Anders Croft did a lovely job laying this specimen out. A joint venture I would say.
