Top 2 Capnia Fly Patterns

Black Perdigon

The Perdigon is more a style than a pattern, and the black Perdigon we stock in the fly shop is an excellent imitation of the Capnia nymph. If you’re a tyer, you can’t skip coating the fly with UV Resin or epoxy. That glass smooth coating increases sink rate dramatically, and gets the fly deeper faster.

Black Caddis

This is a simple fly to carry for the one time every 6 years the trout will rise and take Capnias! Don’t be afraid to tie a Capnia caddis without hackle. The cold water slows the fish down, and they’re not chasing a skittering fly. Leaving the hackle off lets the fly float lower in the film, and makes it more natural and enticing to the slow moving trout.
