DESCRIPTION: L=1".  Black bee without hair on abdomen. 
NATURAL HISTORY: The female chews cavities into branches (some species prefer dried yucca and agave stalks), lays eggs and provisions with "bee bread" for larvae. Males defend nesting sites from other males and mate with females that nest in their territory. For more on bees, see the following boxes: Bee Biology , Bee Dancing, and Africanized Bees
