Acrobasis angusella
Acrobasis angusella, the hickory leafstem borer, is a small snout moth. It was described by Augustus Radcliffe Grote in 1880 and is found in Quebec and the northeastern United States. The wingspan is about 18 mm. Adults are active from May to September.
Larvae feed on hickory trees (genus Carya), including Carya glabra, Carya ovalis, and Carya tomentosa. They bore into the leaf stems, causing the leaves to fall off.
