These are extremely realistic caddis flies and everyone who might see a caddis hatch should own at least a few. The wings are cut perfectly the replicate the natural shape and profile of a real caddis. The antennae are just enough to make these trout flies look real. The brown sedge flies here will replicate spruce moths flawlessly and any other dark variety of caddis on the water. The bottom line is this pattern catches fish, bigtime.
