Brown Drake

Big speckled dusk dun
Trout · GraylingSurface

Big speckled burrowing-mayfly dun of late-spring/early-summer dusk hatches on rich rivers and lakes.

Fish this when

At dusk in late spring or early summer on rich, silty-bottomed rivers and lakes when the Brown Drake burrowing mayfly is emerging in numbers.

Why it works

Its bulk and heavy speckling match one of the biggest duns of the year, and the same fading dusk light that hides you from the fish also blurs the fly's shortcuts — together enough to pull big, cover-holding trout out to feed.
