This helps distinguish males of this species from the male Agapostemon texanus, whose abdomen has metallic or blue-green highlights. In the second phase, the original “foundress workers” cease working and the new workers take over and provision the nest for a second brood of 8-13 males and females called reproductives. Genus: Agapostemon (Metallic Green Bees) Typically, each species of orchid bee has a complex mutualistic relationship with a corresponding orchid in their native range.

In contrast, sweat bees have quite short tongues in comparison to their bodies. Collecting a complex bouquet of fragrances and storing them within the hind tibia represents a considerable investment on the part of male orchid bees.

Also known as virescent green metallic bees, bi-colored Agapostemons are considered "gregarious" -- that is, they band together in communal nests, with each female provisioning her own burrow.
