Early Black Stone
Early-season margin stone
Trout · GraylingSurface
Little black stonefly adult of cold early-season days; fish it dry in the margins and slacks.
Fish this when
On cold early-season days when little black stoneflies crawl and flutter along slack margins and back-eddies, well before any mayfly activity starts.
Why it works
Its small dark silhouette sitting flush in slack water matches the clumsy, low-flying adult stonefly closely enough to draw fish still keyed to a very limited early-season food window.
