California, the Ultra-green Sweat Bee (Agapostemon
texanus) is abundant throughout North America. It favors temperate regions including
the southwest United States and is active from the late spring through fall.
are a shiny green and are called “sweat bees” because they belong to the same
family as many bee species that are attracted to human sweat. Females have a
bright green head, thorax, and abdomen, and carry pollen on tiny hairs on their
hind legs. Males generally have a green head and thorax with black and yellow
bands across their abdomen.
Sweat Bees will excavate deep vertical burrows in banks or sloping soil. Most
species are solitary but will often live communally with other Ultra-green
Sweat Bees. They may share a single entrance but each female will construct and
provision its own brood cells.
