I have been fishing the Mole Fly for at least the last twenty years and it has become my go to pattern for any small mayfly hatch. Its unusual “advanced” wing supports the fly on the surface while the body hangs below like that of a crippled or emerging mayfly. I invented this fly after experimenting with a variety of different CDC patterns. Some of the other ideas spawned during this process are the Loopwing Emerger and CDC Comparadun. Yup, I invented those too. The only problem is that a bunch of other people invented them too. All I can say is that great minds tend to run in the same track. At any rate, tie up some Mole flies and give them a try the next time you encounter tough tailwater fish and see if they don’t do the trick for you too.
