Variations & Comments

It can look like the big caddis, stone flies, hoppers, and more. It floats well and is a killer pattern when skipped back across the surface durning both caddis and stone fly hatches. Also good in orange and black.

Randall picked the best parts of several effective patterns and came up with a fly far better than the sum of its parts. I typically use this to imitate hoppers and large stoneflies but it is much too valuable to be kept in the box when the big bugs aren’t about. When used as an attracter it can be tied in numerous color schemes including royal, green, and black. To do the pattern justice, I’d highly recommend picking up a copy of Tying Dry Flies by Randall Kaufmann.
