Helopicus subvarians (Stonefly) common in New York waters! 6 Replies »Last reply on Jan 9, 2014 by
EntomanI have observed the Helopicus subvarians (springtime stonefly) for over 30 years on many of New Yorks Rivers, such as Beaverkill/Willowwemoc, Ausable (both east and west branch), West Canada Creek, and several others. Most of this time I believed it to be Acroneura nigrita ( Black Willow Stonely) as described by Ernest Schwiebert (Nymphs). Very distinct about the coloring of this Staonely is the last (rearward) sternites are very yellow (Ausable almost orange) while the riest is mostly black top and bottom. The thorax is again very distinctly marked with yellow (orange) with black on top. It is a most beautiflul stonefly, and is see it in May and June. It is well represented by the Montana Nymph is Black with yellow.
