Amegilla is a group of mostly solitary bees, meaning many species in the group will rear young alone. There are approximately 250 Amegilla bees in the genus.
They get their common names from the striking bands on their abdomens. Likewise, the name Digger Bee refers to the way they make nests, where they choose to dig burrows in clay soil. They've been known to nest in mudbricks, too.
The sting has been greatly reduced, although, they rarely use it. As with all bees, it's only the females who can sting.
The males are known to secure themselves to grasses using the mouthparts, and they'll rest like this in groups for periods of the day!
