Striped Sweat Bees are large, metallic green bees that are active all summer on a variety of flowers.

All 4 species of Agapostemon known from the northeast have been found in VT, with two confirmed on iNaturalist. The female of the most widespread species (Bicolored) is distinctive, while the other three species are less common and hard to separate. Like other Halictidae, males don’t appear until the end of the flight period – late July in VT.

Genus level ID

Female Bicolored Striped Sweat Bee are instantly recognizable (with practice), and as a group the males are unique and colorful. Females of the remaining three species are similar to the other shiny green bees – see the Augochlorini page for details.
