Stenopsyche Caddis (large)
Big Japanese mountain caddis
Trout · GraylingSurface
The signature large net-spinning caddis of Japanese mountain rivers; a big buoyant down-wing for the evening rise.
Fish this when
On Japanese mountain rivers at dusk when the big Stenopsyche caddis are up, worked through pocket water and runs as the light fades.
Why it works
Its bulk and buoyancy push a visible wake through broken pocket water that mimics the natural's large fluttering egg-laying flight, giving fish an unmissable target once it's too dark to see clearly.
