Amphibious Assault

A

Mangled Fly, Manistee River

A frog-and-mouse waking fly from the Mangled Fly night box, fished with McCoy's Mouse, gurglers and frogs for nocturnal browns from July through September. The DNR lists amphibians and small rodents in adult brown trout diets; pop and pause it along weedy edges and slow flats after dark.
