Augochlora pura is a solitary sweat bee found primarily in the Eastern United States.
Both males and females have been observed licking sweat from human skin, most likely seeking salt.
[8] According to a study on the bottomland hardwood forest of the southeastern United States, A. pura accounted for about 91% of bees collected in the area.
Unlike other halictids, A. pura does not take flight in response to warm days later in the fall.
In nature, females become active in August and September, mate, and remain in a state of ovarian diapause on moist soil beneath rotting logs.
Their offspring emerge in June, and proceed to found nests of their own by the end of the month.
[8] This waxy coating is thought to be the product of an enzyme-mediated polyesterification of secretions of the Dufour's gland.
[11] As solitary bees, A. pura females do not remain in their mother's nest if she is alive.
They differentiate them from other walls of the burrows through the odor of fresh pollen in combination with the shape and texture of new cells.
Instead of pursuing females in the air, A. pura males wait for them to land on flowers.
Augochlora pura males have been observed to stroke the female's head with their antennae before and during copulation.
Then, they spend their afternoons forming balls of provisions, performing oviposition, and capping cells.
In the laboratory, A. pura even foraged for nectar, pollen, or both at foreign flowers not found near their natural habitat.
A female collect pollen from up to ten flowers to provision a single cell, and these are often from different species.
[10] Inside rotten logs, A. pura has been seen to associate with nests of another bee species, Lasioglossum coeruleum.
A. pura utilize the powdered wood produced by passalid beetles when constructing their nests.
[8] Parasitic nematodes of the species Aduncospiculum halicti have been discovered in the Dufour's gland and genital tract of both males and females.
