While this is a solitary species of bee (don’t work together as a colony), they typically make their nests in close proximity to each other. The nests are made in soil (either in banks or flat ground). Pictured here are males vying for the first opportunity to mate with an emerging female. Dozens of males were observed frantically patrolling this site for a mate. Photo by Marirose Kuhlman on 8/22/19 near Florence, MT.
