The Flash Worm Fly is about as simple—and effective—as it gets. Made by wrapping fine tinsel around a hook, it creates a slim, flashy profile that imitates aquatic worms, midge larvae, and small annelids. It’s a go-to for tight-line anglers who want a fast-sinking, durable fly. This fly is tied on red Octopus hooks: Sizes small (10), medium (8), large (6).
