Jeff Mottern of Harrisburg, Pennsylvania was the apparent originator of this fly in the 1980s. He designed the fly specifically to take the finicky and frustrating brown trout that feed selectively on midges on the Yellow Breeches creek in south-central Pennsylvania's Cumberland Valley. The original recipe called for a size 22 dry-fly hook with dun, brown, and grizzly cock hackles. The adaptability of the fly is apparent and can be tied in a range of hackles (a barred hackle - grizzly or cree - should be included to promote variegation) and sizes. The most productive combination seems to be grizzly, brown, and cream, or grizzly, brown, and dun. The most productive sizes seem to be from 16 through 22.
