For whatever reason we haven't taken any very good pictures of this here bee, Colletes thoracicus. This species is one of two that form huge aggregations in loose or sandy soils in the Eastern U.S. Very cool and for some reason lacking any Bee Nest Parasites (Epeolus) that haunt other Colletes.

Rarity here. This is species was described in the 1950s, named after the town it was collected near and only a handful of specimens have ever been collected that I am aware of. In fact it is so rare that it was on our list of "missing" species, published in 2011.

A blueberry specialist. Look how long that face is...The space between the mandible and the eye is what bee heads often use to separate species. This Colletes validus has a huggggggeeee malar space...other Colletes species essentially have none, the mandible being directly at the base of the eye. Why?

Look at the veryyyyyyy long distance from the bottom of the compound eye to the mandible base (technically this is called the malar space). Few bees show this long a head and it is nearly distinctive within Colletes at least in the north. This is a species that likes to hang out around blueberries and other Vaccinium type things.

Bedraggled Bee. We picture here Colletes willistoni, with mussy hair, something Colletes is prone to. For me this is mostly irritating, in that they don't clean up well for their pictures, for the bees, well, its hard to say, they are an old lineage and apparently great looking hair under all conditions was not their evolutionary priority.
