Sweat bees (family Halictidae) earn their name from the affinity for human perspiration that’s exhibited by some members of the genus Lasioglossum (Triplehorn and Johnson 2005). It may be more accurate to call sweat bees halictids since many species lack this attraction to sweat.
Human sweat aside, members of this family spend their days digging nests in the ground, feeding on nectar, and collecting pollen for their young. Pollen and nectar are collected from a variety of flowers, including this common stinking chamomile (Anthemis cotula, Asteraceae) .
Based on the pointed apex of the marginal cell, pale green color, and reddish tegulae, this halictid appears to be a member of the genus Augochlorella. As the literature suggests, it didn’t seem remotely interested in my sweat.
