Only known from Vermont since 2006, but its occurrence was expected based on distribution records in nearby states. Initially predicted to occur in seep streams in the “thumb” of Vermont formed by the Poultney River. The first visit to such a site in that region at the right time of year yielded the new addition to the state list. Since then, a larva was found in another stream a few miles away. Owing to its under-sampled habitat, this species may be more widespread than records indicate and its flight season is likely to be longer than our limited records indicate.
