Emerger
Drunella Sparkle Dun
Summer BWO sparkle dun
Trout · GraylingFilm
Sparkle Dun for the larger summer Blue-Winged Olives (Drunella) — flush emerger with a trailing shuck.
Fish this when
Fish it on summer afternoons when the larger Drunella Blue-Winged Olives hatch, often the one decent dry-fly window in an otherwise slow, warm day.
Why it works
The flush deer-hair wing and trailing shuck cover the emerging and freshly-hatched stages at once, hedging against fish keyed on either.
