Another species of small Sweat Bee in the genus Halictus. If you’re interested in attempting to identify these bees with a dichotomous key (there are only 10 species in the Northwest, so it’s not too difficult!), check this one out here. Once you learn more about these little guys, you start noticing them everywhere!
