May be Vermont’s least cosmopolitan baskettail, with a distribution favoring large river valleys and other low-elevation sites. Essentially absent from piedmont and mountain biophysical regions, where E. canis and E. spinigera are more common. The taxonomic difficulties of this species are not encountered in Vermont since E. semiqquea and E. costalis have not been found in Vermont (yet). Both clear and mark-winged males are netted in Vermont, and smoky-winged females are regularly encountered. Rutland County is a stronghold for the species, which is also found in the Champlain Valley and at locations not far from the Connecticut River.
