Guess The Mystery Fly - Clue #6

It's time for this years Blue River Fly Classic "Guess The Mystery Fly" game.  To enter you must be planning on entering the Blue River Fly Classic that takes place March 5th.  To submit your answer you can post in the comments section of this blog, or respond to the post on Blue River Oklahoma All Trout Fishing on Facebook, reply to the post on the Blue River Fly Fishers group on Yahoo, or send your answer to fishingcowboyblue@yahoo.com

The winner will be the first correct guess received.  The winner will receive a practical piece of fly fishing gear and that will be awarded at the Fly Classic on March 5th. 

Okay, we are going to make this a bonus clue so to speak with there being actually two clues within one.  There are two words in the mystery flies name and the name is often followed by the word nymph.  Either answer will be accepted as long as the name is correct.  However, the mystery fly is intended to imitate a caddis larva.

Good luck!
