The Puterbaugh Caddis was developed by Don Puterbaugh, a long time guide on the Arkansas river in Colorado. This is a high floating and versatile pattern. It can pass for a caddis or terrestrial. I have used this pattern for years and sometimes it is the only caddis imitation you need.
Hook - dry fly size 12-18
thread - black 8/0 or smaller
body - black 2 mm foam, ¼ “ wide
