The Squirmy Worm with a Tungsten bead is an exciting fly to throw at Trout. The extra weight of the Tungsten bead and the silicone worm help this fly get down in the water faster. The undulating action mimics a real worm so get ready for that quick take. Trout, and other species, cannot resist this worm imitation when they see it. With 5 colors to choose from you will surely find what the fish are looking for. Choose a single color set or our 10 flies set with 2 flies in each of the 5 colors. We tie these flies on #12 hooks.
