Interesting to learn that Jason collected R. fuscula April 1st. My hatch chart for the East Branch Delaware needs to be corrected, as I had R. fuscula hatching much later. Schweibert mentions this insect on p.83.
Lightly on the dimpling eddy fling;
the hypocritic fly's unruffled wing.

I may be missing something here, but it appears the Rhyacophila fuscula which Jason collected and photographed were (was?) in larval stage, and therefore wouldn't be emerging until later, so perhaps your chart does not require revision.
