There are many versions of this fly out there. I found 4 in Flies for Trout by Stewart and Allen. This particular pattern was designed by George Harvey, Penn State fishing instructor and author of Techniques of Trout Fishing and Fly Tying. I think this fly dates to the 1930s. Sulphur Mayflies are small so sizes 14 -18 are appropriate.
Ed McCoy of Michigan came up with this mayfly pattern several years ago. It’s a variation of a parachute dry fly in that the front and rear sections of hackle are cut from the para post to form a pair of spinner wings.
The Hemingway Caddis is a variation of the Henryville Special developed in the 1930s. Mike Lawson created the variation for Jack Hemingway, son of the famous author Ernest Hemingway, for fishing the Henry’s Fork of the Snake River in Idaho.
