Dufourea novaeangliae


Dufourea novaeangliae is a solitary ground-nesting bee that lives in the eastern U.S. The range of these bees is presumably limited by the availability of its only known pollen source, the pickerel weed (Pontederia cordata). This is an aquatic freshwater plant, and thus D. novaeangliae nests are often found in sandy soil near ponds and streams [1]. Most female D. novaeangliae build a single nest in a season, with the offspring over-wintering as prepupae in a cocoon [2]. In the spring, males emerge approximately one week prior to females [2], and they patrol pickerel weed flowers or nesting aggregations for receptive females to mate with [1].

D. novaeangliae is in the subfamily Rophitinae of the family Halictidae [3]. They are thus basal to the sweat bees of the family Halictinae [3,4]. Most species in this subfamily specialize on one or a few host plants, with closely related species of Dufourea sometimes specializing on distantly related plants [4].
