Low-riding glide-water olive
Trout · GraylingSurface
CDC-winged BWO dun that sits low and flush — deadly on smooth glides during an olive hatch.
Fish this when
On smooth, slow-moving glides during a Blue-Winged Olive hatch, when fussy fish are sipping duns off a mirror-flat surface.
Why it works
With no hackle to prop it up, the soft CDC wing settles the fly low into the film exactly like a real dun caught in the surface tension, while trapped air in the fibres keeps it from sinking outright — the low, half-drowned posture fussy glide-water fish expect.
