I saw this streamer pattern tied for the first time this summer during TU's national meeting in Michigan. Unfortunately I lost my notes so I can't give the creater of the pattern the credit that he deserves. This streamer was one of my top producers this fall. The pattern was originally designed to target trout swimming in the waters of Patagonia and was tied to imitate the Pancora. Pancora are a crustacean which sorta looks like a mix between a crab and a crayfish.
Luckily the colors do a pretty good job matching our local crayfish species. I fish this fly in a heavily weighted version and try and bounce it along the bottom. It works well being stripped like a traditional streamer as well.
