All records of this species in Vermont are subspecies A. f. violacea, known as the Violet Dancer. Found at mid to low elevations in much of Vermont where it is often, but not exclusively, in association with flowing water. Occasionally found at ponds. Mountainous areas with higher gradient streams or rivers lack this species. The scarcity of records in the Champlain Valley seems somewhat anomalous and may result from a lack of appropriate survey effort or relatively few streams of the right substrate and gradient.
