The biot rock worm video

 Here is the video for the biot rock worm I tie and use. It is a rather simple tie, and quick, so don't be fooled by the time of video. I used this pattern this past black Friday and it is the fly that the large male brown trout took. It is a pattern I use often on freestone streams that have a lot of caddis.
   When tying these. You should tie ones with a black or dark brown biot on top also. The rock will color up when it gets close to time for metamorphosis. In the winter I use all green and the spring and summer, I use ones with the dark front upper.
   I like to fish these flies, dragging on the bottom. Sure I lose them, but I have found its the best way to fish a rock worm pattern.  Well enjoy the video and tight ties! p.s. The light shade green sharpie is key, so dont forget to pick one up.
