Dry FliesBPS Spent Caddis

Natural Behavior: Exhausted adults collapse on the surface film after egg-laying, wings flush and drifting helplessly downstream, often accumulating during evening spinner events.

Where Trout Eat It: Fish selectively key on these low-profile, spent adults drifting in surface seams and foam lines during post-hatch feeding periods.

How to Fish It: Dead drift with wings flush to the film, imitating the complete helplessness of collapsed adults unable to escape.

Best Water: Most productive in foam lines, slicks, tail-outs, and current seams where spent caddis accumulate after concentrated egg-laying flights.

Strike Type: Confident, methodical sips as fish capitalize on easy, concentrated calories from exhausted adults trapped in the film.

Rigging Suggestions: Rig this fly on its own or in a tandem dry fly setup with another caddisfly imitation.

Seasonal Timing: This pattern is particularly effective from late through when caddisflies are most active. Use this fly when you observe trout feeding on spent caddisflies, especially during a caddisfly hatch or in the evening when caddisflies are most active.

Pro Tips: The elk hair wing of this fly provides excellent visibility and floatation. Its hackle also aids in floatation, making it ideal for fishing in faster currents.
