At one time labeled as: "Premium Skunk Repellent," the Idyl's Chrome Chironomid is one of those fly patterns that wasn't designed to match any hatch. Yet, it was designed to match hatches of many hatches of Chironomids. As the real critters hatch they become very shiny. The Chrome Chironomid is kind of goofy looking, but not when stuck in a trout's jaw. They work.
