The Squirmy Wormy is a simple yet deadly fly pattern that imitates aquatic worms and annelids, especially effective in off-color or high-water conditions. Its soft, elastic rubber body creates lifelike movement and is effective worldwide for trout. The pattern is typically tied on a curved or jig hook with a weighted bead head for quick sink and consistent bottom contact. Though sometimes controversial among purists, it’s a go-to fly for guiding situations, or when bug activity is minimal. Available in bright pinks, reds, and natural tones, the Squirmy Wormy shines as both a lead fly and dropper.
