Baetis mayflies hatch when the weather is miserable, which in the Driftless means you will be standing in drizzle feeling sorry for yourself right until the first trout rises. Then every trout rises. This pattern matches the little blue-gray sailboats that drift down spring creeks by the thousands, and the trout eat them with the methodical precision of someone working through a buffet line.

The Hex Hatch: After Dark on the Great Lakes

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.

Nymph or Dry? The Decision That Changes Everything

Ninety percent of a trout's diet is consumed subsurface. Yet ninety percent of the magazine covers show a dry fly floating on calm water. The decision between nymphing and dry-fly fishing isn't about preference — it's about reading the situation and making the choice that puts your fly where the fish are actually feeding.
