Flav Sparkle Dun

Small summer drake sparkle dun
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.
