That is funny Byron, I have been working on serendipities too. Have not come up with anything to post yet but so far am leaning toward using crinkled Z-Lon for wing but have not settled on anything for sure yet. I do like the coloration you have there.
Planet Trout has some very cool Serendipity patterns at http://planettrout.wordpress.com/2011/04/29/caddis-interrupted/. I really like the way he’s combined different colors and types of materials twisted together for the body. It sparked my imagination.
It is meant to be fished in the water column from the bottom to just under the surface. If I were going to suspend it, I would probably use snowshoe hare for the wing. None of the materials in this design float with consistency. I will tell you that variations on this pattern, in chartreuse, have caught a lot of nice trout for me during the Brachycentrus hatch that comes off on the Lower Owens in late March through the beginning of April - I took about twelve nice Browns and Rainbows out of here, while a guy with a spinning rig was watching me from the opposite bank. I think I converted him…
