This is my first tutorial. It’s for a general pattern for adult caddis dry flies and can be adopted for any size or colour. This particular version is deadly for trout in Swedish streams and rivers during hot summer days when a small grey caddis can emerge and swarm in large quantities. These days trout can be particularly selective in their feeding but this pattern seems to be working well. There’s no point for a fly to look realistic and pretty, if it doesn’t float correctly and actually catch a lot of fish. This pattern was developed particularly with this in mind.
