brown bee - Andrena crataegi
Decorah Prairie, Winneshiek County, Iowa, USA

Size: 10 mm
I think this brown bee is in the Genus Andrena because it has distinct facial foveae. I did not see very many brown Andrena bees as I looked through the guide pages, but enough to know I cannot take this bee down to species. My best "guess" was Andrena wilkella. I did read that it is very difficult to nail down species from just photos in the Andrena genus.
