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 member of the difficult to identify Trachandrena subgenus of Andrena. I think that I have the females sorted out (more or less) but the males...oi! This specimen from Maryland. Picture by Amanda Robinson.

Andrena forbesii from Maryland, thanks to Ann Simpkins for photoshopping

An odd, dark Andrena bee of deep sandy areas that comes out in the middle of summer

Andrena fulvipennis "“ A very rare species this male was captured in an old sand pit in Anne Arundel County, Maryland. This species is only found in deep, permanently sandy locations. Picture taken by Brooke Alexander.

Two different specimens of Andrena geranii. A northernish species that appears to be a specialist on ....geraniums. Notable is the slight blue metallic sheen to the body. Aaman Dengis and Brooke Alexander took the pictures.

Not the best lighting, but this is Andrena gnaphalii....a interesting Andrena with a green tinge. From the Channel Islands off the coast of California. Photo by Anders Croft.

Is the scientific name implies (helianthus = sunflowers), Andrena helianthi is a sunflower specialist. Not just the annual sunflower, commonly now raised to produce sunflower seed and sunflower oil, but also the many species of perennials and flowers, which are well deserving of spots in our gardens.

Echinacea. This medicinal plant is widely planted and tinkered with by gardeners and breeders. But, it really is a prairie species and when in its habitat, like the Badlands, big bees like to forage on it. Hey, look, here's one in this picture! Andrena helianthiformis. I suppose this means "looks like A. helianthus, but...is not" in Latin.

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.

Ah, Andrena vicina one of several Andrena or mining bees that feed their babies almost entirely the pollen of blueberries. This large, honey bee sized Andrena is noteworthy for the dark pollen carrying hairs on its legs.
