Gary LaFontaine spent years studying caddis underwater with a diving mask and what must have been extraordinary patience, and he discovered that emerging caddis pupae are surrounded by a gas sheath that makes them sparkle as they ascend. His Sparkle Pupa replicates this effect with Antron yarn, and the result is a fly that catches trout when the surface is covered with caddis and nothing else works. It is the rare fly pattern that was designed from observation rather than imagination, and the fish can tell the difference.

Emerger Patterns: Fishing the In-Between
Trout eat more insects during emergence than at any other stage. Emerger patterns — flies that imitate the critical moment when a nymph transforms into an adult in the surface film — are the most consistently effective dry flies in fly fishing. Here is the science and the technique behind fishing the in-between.

The Winter Guide: Cold Water, Warm Hands, Willing Fish
Winter separates the dedicated from the fair-weather crowd. The rivers are empty, the hatches are tiny, and the fish feed in slow motion. But they do feed — they have to. And the angler who understands cold-water metabolism, midge biology, and the art of slowing down will find winter fishing not just productive but deeply rewarding.
