Micro Suspender Caddis - Caddis Dry Fly. lighter dressed than the more common Caddis fly imitations but very popular in many of our Canadian rivers and streams. A tasty combination of natural deer hair for wings and fine black dubbing for body. I personally fished Micro Suspender Caddis fly on the Grande River in Ontario and had one of the most productive Brown Trout days I can remember. You have to have one of these on you fly patch.
