I named it a "teardrop wing" because of the shape and hooding effect on the body. In it's finale position it looks like a teardrop... I've never seen this winging technique used on any other fly. Tied in my way, it incorporates the hackle/legs and wing all in one step...

VARIATIONS: I developed the fly for use on the Delaware River here in New York. We have lots of Apple Caddis with these very light tan wings. I also tie them without wire or bead heads and of course you can change the dubbing and wing colors to imitate any other caddis emerger....
