Status:

One of our earliest spring bumblebees. Unlike some of the other species it is still very common in most parts of the eastern United States. By late June/July you can see that the nests are producing males and beginning to wind down the season. (S. Droege, pers. comm)

Description:

Nests are categorized as existing cavities, and social behavior is categorized as primitively eusocial or semisocial (Selfridge et al., 2017).

There are 49 records in the project database.
