Augochlora pura is a solitary sweat bee found primarily in the Eastern United States. It is known for its bright green color and its tendency to forage on a variety of plants.

Within Halictidae, 4 subfamilies, 81 genera, and over 4,000 species have been defined. About 1,000 of the species in the genera Halictus, Lasioglossum, Augochlora, and Augochlorella, are eusocial.

Over most of the range of the species, their entire bodies are a shiny, bright green, in contrast to many Lasioglossum species such as L. zephyrus, which are a dull metallic green. Male Augochlora pura tend to have darker mandibles and may be slightly more bluish than females, but otherwise, males and females... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Pure Green Sweat Bee is recorded against all the insects logged in Philadelphia (15 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
