More common than its congener, well distributed on rivers with more moderate flow and perhaps on certain lakes as well. Flies in most biophysical regions. Though no Vermont records exist along the Connecticut River in southern Vermont, low numbers of exuviae have been found along much of the New Hampshire side of the river (Hunt et al. 2010). Like its congener, the best way to find and catch this species is to stand at stream edges and wait for one to fly by.
