The Rainbow Biot Sow Bug was developed on the tailwaters of the West by Utah fly fishing guide, Jake Ricks. Fish in many tailwaters make sowbugs the staple of their diet and this pattern seems to fool them nearly every time. The mix of translucence and various colors is virtually irresistible. Jake tells us that he once caught the same fish twice in about 10 minutes on this fly on the famous Lower Provo River tailwater. Sounds pretty irresistible to us!
