Tachopteryx thoreyi (Gray Petaltail)Evidence in Vermont comes from a single sight record by a credible odonatologist, Frank Carle, in suitable habitat at Grout Pond in the state’s Southern Green Mountains on 15 July 1995. One other report from Groton State Forest during the 1970s lacks substantiation. Vermont would be at the northern edge of this species’ range.

Often an obvious dragonfly at its woodland seep breeding sites, Gray Petaltail remains in large part a mystery (or absent) in the state. Lacking incontrovertible evidence, the status of the East’s only Petaluridae remains for the purposes of this atlas “unknown” in Vermont.
