I'm getting ready for an upcoming fly fishing trip to the Delaware River with my son Scott by tying a few Isonychia emergers.


Matt Grobert's Iso-emerger is a simple and fun fly to tie. The fly below is tied on a size #10 Allen scud hook with only three materials; zelon for the shuck, Iso custom blend DK#25 dubbing for the body and some natural deer hair for the wings.



I like to add a front hackle of brown grizzly to the pattern to give the impression of legs.
