Trout · GraylingFilm
Sparkle Dun for the Flav (Drunella flavilinea) — the smaller olive western drake of summer.
Fish this when
Fish it during the Flav hatch on western rivers in early-to-mid summer, typically a short, intense morning or evening window that pulls steady rises.
Why it works
The sparse, flush profile reads as a smaller, size-matched cousin of the bigger Green Drake emergers, so fish stay confident instead of growing wary of an oversized fly.
