Balloon Caddis

Foam-ball sedge pupa
Trout · GraylingFilm

Foam-ball head suspends the body in the surface film — imitates the caddis pupa hung in the meniscus at the moment of emergence.

Fish this when

Fish it during a dusk caddis emergence when naturals are punching up through the meniscus fast, and trout are taking pupae hung in the film rather than chasing skittering adults.

Why it works

The foam ball buoys the fly without a hackle collar propping it up, so the body hangs at the same tilt and depth a natural pupa holds in the meniscus moments before it breaks through — a suspended posture a standard hackled pattern can't fake.
