Andrena macra, f, face, Kent County MD

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. Teacher-wise, I recognize the species by the high pit density on the abdomen, many pits appear to touch each other. And by the notably kinked tibial spur. And there you have it, next time someone wants to know how to identify the species you are empowered. Photography by Brooke Goggins.
