There is a group of bees in the genus Andrena that form a fairly distinct subgenus called Tracandrena. They are notorious for being difficult to separate out and, in particular, the males all look pretty much the same. Sam Droege has an Excel spreadsheet that helps distinguish females. This species is fairly common in the spring, when it collects pollen from a wide variety of woody plants. (S. Droege, pers. comm.)
Nests are categorized as ground burrows, and social behavior is categorized as solitary to communal (Selfridge et al., 2017).
There are 27 records in the project database.
