Video: How to Tie the Grannom Caddis Pupa

American grannoms (Genus Brachycentrus ) are caddisflies that provide some wonderful springtime hatches, often emerging alongside mayflies. (Click here to read Ted Fauceglia’s excellent rundown on grannom hatches.) Trout often focus on the vulnerable pupae, which must swim to the surface and then struggle to emerge as winged adults.

In this typically great video, Tim Flagler of  Tightline Productions shows you how to tie a buggy, effective imitation of the grannom pupa. I love the way he uses a single clump of pheasant-tail fibers to create the back, wingcase, and legs of the insect.
