Known from four sites in Vermont, all fens under conservation protections. Conditions at each site vary slightly, with one, a gramminoid fen, having a bog pond and another with little in the way of open water. Additional sites for this species may yet be discovered. One strategy for finding W. fletcheri is to look for adults in sunny woodland openings near the peatland. An addendum to this species: Moderate effort has been devoted to locating its congener, RInged Boghaunter (W. lintneri), in Vermont without success.
