What is this? - Paragnetina immarginata
Middlefield, Hampshire County, Massachusetts, USA

Size: approx 1"
Found this on the riverbanks at the Keystone Arhes. There were many exoskeletons that were split open and looked similar to this body style, but this one was still alive although barely moving.

Good call
This is a perlid stonefly nymph, and does appear to be Paragnetina immarginata. This specimen was in the process of molting into an adult, and that is probably why it seemed sluggish. (The degree of enlargement allowed by these photos is superb, and you can see the old exoskeleton separating around the eyes in #320787.) The empty shuck is from the same species.
