Caddis larva are one of the most prevalent insects in rivers, and are particularly loved by trout. In the real world caddis pupa have dark wing pads and antennae that are very noticeable, and have a body and legs that undulate enticingly in the water. This fly is tied on a barbless jig hook and has a mottled tungsten bead to look as natural as possible, while keeping the fly in the feeding zone. Finally, black wing pads offer a striking contrast to the body color. All-in-all, this has proven to be one of the most effective caddis pupa patterns we have ever designed and tried, and we have found that trout absolutely love RIO's Puparazzi fly - and so will you.
