Tan CDC Czech Nymph


A general purpose nymph that is also an excellent imitation of spotted caddis larvae and and scuds. The CDC captures a nice bubble of air under the fly, and the body looks incredibly buggy. This fly is a perfect imitation of spotted caddis (Hydropsyche) larvae.


Vary the color to match nymphs and larvae in the area you are fishing. Good colors include tan, brown, olive, and caddis green.
