In this fly tying video from Tightline Productions, Matt Grobert ties his version of the Chimarra Caddis Larva, a super simple fly pattern (just the way I like them). Grobert demonstrates how even such a simple pattern can make for a very attractive and imitative pattern that trout will find hard to resist.
The Chimarra caddisfly, also known as the little black sedge, is common to the eastern and Midwestern United States. In it’s larval stage, the Chimarra caddis is bright orange to yellow and darkens to black during emergence in the Spring (weird I know). Fishing this bright Chimarra caddis larva pattern in late February and March, the months leading up to the hatch, is often very effective. This pattern works great as a dropper off a heavier nymph.
