Isonychia Parachute

A

Isonychia is one of the Au Sable's Big Five, hatching in two peaks, June and September, from mid May to the end of September. The nymphs crawl out to emerge, so Michigan guides fish nymphs and spinners more than duns; use this parachute as a spinner or searching dry on evening riffles, and midday in fall.
