Flies / Dry fly

Ed McCoy, Mangled Fly, Manistee River

Gray Drake nymphs crawl out to emerge, so the spinner is the only stage worth imitating, and this is the Michigan pattern for it. Spinner flights happen every evening from 7 pm until dark from the third week of May through July on the Muskegon and Pere Marquette, and in June on most northern rivers. Fish it over riffly current where the mating swarms drop.
