Trico Dun
Simple dark micro-dun
Trout · GraylingSurface
Minute dark Trico dun of late-summer mornings — a dense, technical hatch.
Fish this when
The same early trico dun window, kept in reserve for the days when the comparadun starts getting refused on heavily fished water.
Why it works
Its plainer, low-key dark profile reads as just one more anonymous dun among thousands, exploiting the fact that fish keyed onto a blanket hatch are matching a general impression, not inspecting individual flies.
