I am by no means a fly pattern historian. I leave it to others to delve back through the annals of fly tying. The fore and aft style fly pattern is reputed to have originated in England over a century ago. Most patterns (save those with new synthetic materials) probably had multiple originators in the far corners of the fly tying/fishing world.

The fore and aft is often offered up as a midge cluster. Well, that seems fine for a very small pattern, say size 16 to 20, but my experience with say the Renegade pattern is it has done amazingly well in B.C. lakes as a Caddis pattern beneath the surface. I recall a small, remote lake near Wavy L. that to this day afforded some of the most amazing fly fishing I have ever experienced. The Renegade pattern was in tatters, with the tinsel and rear hackle trailing behind. There were no chironomid/midge in sight. Only, Caddis/Sedge were emerging and skittering. As tempting as it was to put on a large dry Caddis pattern, the sunken Renegade was intoxicating to the fish and to me. I will never forget the fly line zipping through the water as the Kamloops took the fly and jetted off across my path. 

Whether the body in tied thinly or rather plump, like the Renegade, experiment with the fore and aft hackling on a pattern. Try it as a searching pattern where exact dry fly /emerger pattern presentations are not called for. Lakes and busy surface streams would be good choices. The hackles can be the dry fly quality feather or even a softer hackles for a busier look. I have include a Renegade I tied and a Stick Fly (midge) pattern that shows Ostrich Herl for the hackle.
