Dufourea novaeangliae

(Robertson, 1897)

Pickerelweed Shortface

Dufourea novaeangliae is a solitary in the , commonly known as the Pickerelweed Shortface. It is an oligolectic () exclusively associated with pickerelweed (Pontederia cordata), a semi-aquatic . The occurs in north-eastern and north-central North America, with confirmed records from Connecticut, Massachusetts, Maine, Pennsylvania, Maryland, Illinois, and Vermont. It is phylogenetically distant from and possesses the smallest odorant receptor repertoire (112 ORs) among fully sequenced bee .

Habitat

Aquatic and semi-aquatic environments where pickerelweed (Pontederia cordata) grows, including pond margins, lake shores, and slow-moving water bodies. Soil-dwelling nesting biology confirmed.

Distribution

North-eastern and north-central United States. Confirmed records: Connecticut, Massachusetts, Maine (Waldoboro), Pennsylvania, Maryland, Illinois, Vermont. GBIF records indicate presence in Vermont.

Diet

forager on floral resources of pickerelweed (Pontederia cordata). Oligolectic confirmed by repeated association.

Host Associations

  • Pontederia cordata - obligate pollen/nectar sourcepickerelweed; sole confirmed

Behavior

Solitary nesting confirmed. Both sexes visit pickerelweed flowers. Oligolectic foraging strategy—specialized on single rather than pollen collection.

Ecological Role

services for Pontederia cordata. Viewed as potential alternative pollinator to in wetland . Contributes to reproductive success of semi-aquatic vegetation.

Human Relevance

Research interest due to phylogenetic position as most distant sequenced relative to . Studied for comparative of olfactory receptor evolution and eusociality origins. Potential value as managed for wetland restoration or pickerelweed .
