Also known as the Chuck Kraft Nymph, this pattern is a great searching fly.
Designed to mimic both caddis and stoneflies, this pattern is incredibly effective on many rivers.
Kind of like a Woolly Worm, or a Yuk Bug, or a Girdle Bug, this fly just has a plain ole buggy look to it.
Grizzly hackle provides a look of legs, or pupa starting to emerger.
Mallard Flank is used on the tail to provide a variegated type look, and a black chenille body gives it that classic nymph look while casting a big silhouette.
