The Maine snaketail is found in clean, fast-running trout waters that have adjacent forest canopies partially overhanging the stream. They are found in only two watersheds in New Jersey that are separated with little to no suitable habitat nearby with which to expand their range. The species’ overall range is from New Brunswick, Canada south to Georgia.


Larvae are predatory and adults feed on other invertebrates.


This species emerges in mid-May and juveniles are flying a few days later. The best time to see the adults is in June, but they are active through the first week of July.


The Maine snaketail is considered a species of Special Concern in New Jersey.
