Red Quill Emerger from Orvis
I discovered that there is essentially, no real patterns out there for this black sheep of the Mayfly world. I dug deep into some circa 1950 stuff, I went East coast, West coast and read some Latin. I waded through some incredibly bad web content and worshipped all the groovy new fly catalogs.and basically got skunked. Weird for a bug I see so often. Latin wise it seems to be in the Rithrogena gang with March Browns, but the nymph patterns are all very fat. Most of the Hendrickson patterns look a whole lot closer size and color wise but I'm afraid they are bloods and not crips. I'm not looking to get wacked here for crossing a line with the Ephemera gang. Truth is, I still have no idea what it is we are trying to imitate, I just know there is not a nymph pattern of what I'm not sure I'm seeing. Superflys (tung, soft hackle PT's) work all summer long in the right water type so maybe there isn't a better mouse trap after all.
A friend of mine was fishing size 12 PT's with an over sized bead one summer when the Quills were around and he was killing it deep. Something or other he read he said. "These bugs worked real hard at getting back under things on the bottom in fast water" he says. Real similar to the March Browns back East, but no closer. Time to call my buddy the Bug Man. Either way, all this research and thought spawned that Bead Head Red Quill for use this summer.....probably wont work, but I've got 3 dozen of them.
