Gold-Green Sweat Bee Augochlora pura, known as the pure gold-green sweat bee, is a solitary sweat bee native to the eastern United States with striking green iridescence. This species is an important native pollinator in eastern deciduous forests and other habitats. It emerges in spring and remains active throughout the summer and early fall. As the common name of this group suggests, these sweat bees are attracted to human sweat, which they lick to consume salts.
