In the March 1989 issue of Fly Fisherman magazine is an article called ?The Mighty Midge Pupa? written by Eleanor I Schaeffers (she and her husband ?Dutch? owned Terminal Tactics, a now defunct company that used to make a complete line of tippets and accessories). One of the patterns that caught my eye was the ?Middepth Pupa?. It is really just a simple thread midge that has given me great success on many rivers in the Rocky Mountain west. I like simple and easy flies, and this one is all of that.
