Digger Bees typically live solitary lives, and they do not build colonies. Andrenid bees are characterized as hairy-bodied, short-tongued, burrowing insects. Their burrowing habits create long, vertical tunnels, which branch off to individual cells provisioned with pollen and nectar. These bees, despite being solitary creatures, will occasionally build nests near each other in bare-ground areas. Both male and female Digger Bees will overwinter in these burrows.
Colletid bees nest in various ground cavities and have a habit for smoothing nest walls with their secretions, earning them the names of plasterer bees or polyester bees. They create straight tunnels with numerous short branches, each containing multiple cells.
Halictid bees are similar to Andrenid bees in terms of nesting. Occasionally, large populations of Halictid bees will nest near each other, sometimes sharing the same tunnel to the surface. Their development process lasts about 2 weeks. These sweat bees can become an annoyance when they become attracted to moisture or perspiration. They sometimes leave a mild sting, particularly if they are brushed away.
