Helicopsyche borealis (Speckled Peter) Caddisfly Pupa
View 13 PicturesI'm calling this one very tentatively Helicopsyche borealis, with some big caveats that I might be wrong.
It seems to key fairly easily to Helicopsychidae, except at the last couplet in Merritt & Cummins (5th ed) it's supposed to have “anal processes short and straight, each with several mesal (Mesal: Toward the middle.) setae (Seta: Little hairs on insects.) and 2 long apical (Apical: Close to the apex; tip or end.) setae (Seta: Little hairs on insects.),” whereas this one has VERY short, straight processes with 3 long apical (Apical: Close to the apex; tip or end.) setae (Seta: Little hairs on insects.) and no mesal (Mesal: Toward the middle.) ones.
Additionally, the only species of Helicopsychidae documented in this region is Helicopsyche borealis, which is supposed to emerge much later in the summer.
