I was first introduced to this pattern through a musty old pamphlet entitled How to Catch a Fish with O. C. Tuttle's Devil Bugs. I found the molding 22-page booklet in a box of donated fly tying materials that I was sorting for my local Trout Unlimited chapter. I took the yellowing pages home with me and read them cover to cover. Inside were drawings and descriptions of scores of devil bugs tied to catch everything from bluegills to tarpon.
