Numbers
~400 spp. in 10 genera of 2 tribes in our area, ~3,500 spp. in 55 genera of 3 tribes worldwide(1)
Range
one tribe is cosmopolitan, another is primarily neotropical, and the third is restricted to the Old World (mostly warmer parts); S. American fauna shows the most diversity at generic level(1)
Remarks
Most species nest in burrows in banks or in the ground (Augochlora uses partially rotten logs). Some are primitively eusocial; in such cases usually a female guards the entrance to the burrow by plugging it with her head. Generally the main burrow is vertical; it sends horizontal branches, each branch ending in a solitary cell. (2)
