Green Drake
Large mayfly dry
Trout · GraylingSurface
Large pale mayfly dun for the Green Drake hatch (Ephemera guttulata in the East) — a brief, prolific early-summer emergence that pulls big brook trout up on freestone rivers and northern lakes.
Fish this when
Late spring into early summer when the Green Drakes emerge, often in the afternoon and at the evening spinner fall (the Coffin Fly).
Why it works
A rare big-protein mayfly that brings even larger, cautious fish to the surface during a short, intense window.
