Peak: last week of May through first 2-3 weeks of June

Reported start dates differ: one shop gives the last week of May through the first two or three weeks of June, a short hatch of two to three weeks at most; another gives roughly May 15 to June 5 across Pennsylvania freestones, a 7-10 day window at any one reach, moving upstream from Coburn and Weikert; a third says early June. Coffin Fly spinner falls draw the heaviest feeding. Called the main event.
