Lasioglossum cressonii (Robertson, 1890) are part of the genus sweat bees Lasioglossum that come from a diverse subfamily Halictidae. Halictidae exhibit eusocial hierarchy behavior which is interesting given that eusociality in this group is hard to evolve and easy to lose. L. cressonii is found throughout North America. Their diversity makes them a difficult bee to study and there is a bit of dispute over how many subgenera exist. L. cressonii have been shown to be important pollinators for apple trees and many other North American native plants.
