I have been playing with some bead caddis flies lately. These ones on the right was a test and I sent them to a friend in Colorado to try and they caught a mess of browns. These are quite simple to tie. I used a normal scud hook and pink seed beads. They were tied on a size 16 and the dubbing I used was black squirrel brite from spirit river. The thread is normal mono type. On the heads I will hit it really good with a piece of velcro and tease the fibers towards the back to represent legs
Here is another version that has not been tested yet. Same concept with materials but I used green and pink beads and the head is Medium Olive Squirrel Brite. I used a pink butt again as a test an waiting to hear how they worked. You can use several colors for the head. Below are some of the other colors I have used. Again these are all squirrel brite for the heads.
