Agapostemon virescens lead a very unique lifestyle - living in underground communal nests, with up to 30 individual females sharing the same space. These tricolored metallic bees have an intricate defense system which consists of assigning roles; while some female bees explore and gather food, at least one always stays behind as gatekeeper! Interestingly enough, this species cleverly protects their nest from predators by making sure that they always has someone on guard duty.
During late-July to early-August, a second generation of A. virescens emerges that is both male and female. With no place in their natal nests for the males to go, they seek shelter elsewhere - hosting bee slumber parties where huddles are formed! The females take advantage of this time by sipping on flowers like New England aster, goldenrods and sneezeweed so as to survive winter without having any need build nests or lay eggs during fall season. Sadly though when temperatures drop these mated females enter hibernation while males die selflessly protecting them until spring arrives again next year.
