Dry fly
Ephoron Dun (12-14)
Ghost-white blizzard-hatch dun
Trout · GraylingSurface
Ghost-white late-summer dun of the White Fly emergence — a blizzard hatch at dusk on US rivers.
Fish this when
At dusk in late summer during an Ephoron White Fly blizzard hatch, when so many duns cover the water that fish feed on rhythm as much as on individual flies.
Why it works
The stark white body stands out against dark water in fading light, which matters when the hatch is dense enough that being seen by you is as important as convincing the fish.
