There is magic in the Zeppelin Caddis. Have you ever been in a blizzard caddis hatch, with fish porpoising all over but ignoring your fly? They are probably on the pupa or emergers. The Zeppelin Caddis, with its detached bubble-shaped body and scratchy thorax, uniquely combines a low floating profile like an emerging pupa with great visibility and buoyancy, and it has cracked the code on fussy eaters from the great tailwaters of the East to brawling Western streams. It’s also a great attractor pattern, because it shows the fish a profile they likely haven’t seen before.
