The history of this fly is covered in depth in the article How to invent a fly pattern. But since a few asked me for an SBS while this was going on back in December 2022, I thought I'd bring you the fly pattern here.
It's a fairly simple fly, but thanks to its colors and the ribbed segments it appears nice and pretty fancy.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
