hey pt…i really appreciate your rock worm. sure to fill a spot in anyone’s fly box.
is the rib silver?
Very nice tie Planettrout.
Interesting use of the deer hair collar - that’s the first I’ve seen tied in front of the bead. Are they representative of legs?
cheers,

Moscow,
This pattern was designed by Sandy Pittendrigh, the ADMINISTRATOR at Montana Riverboats. He uses tan coastal deer hair and natural ostrich herl. He also uses Lazer Wrap for the body which is no longer available from Wapsi. I believe the deer hair gives the illusion of motion, especially bouncing off the bead…net spinning caddis have very short legs…

Perhaps you’ve heard about the big Bob Jacklin fish, caught on Green Rock Worm:
Catching a fish like that is rare enough…let alone in front of a well-equipped video crew.
… for posting the link to Jacklin’s big brown. I’ve seen stills of the fish, but didn’t know about the video. That was probably a Hegben Lake fish on a spawning run up the Madison ??

NOW BACK TO YOUR REGULARLY THREADED DISCUSSION OF A NEAT CADDIS PATTERN !!
John,
He caught it on the section of the Madison between Quake and Hebgen

Do you have a list of materials for that Rockworm?
Here’s Bob Jacklin tying his version:

Bob caught that fish between Quake Lake and Hebgen dam, just a bit upstream from the Cabin Creek camp ground.
If you’ve ever been there you can recognize exactly where it is from studying the video.
The opposite (South side) bank looks like prime holding water, but it’s impossible to wade to, and it’s also (nearly)
impossible to motor up that far (from Quake Lake) due to fast water and shallow gravel bars.
…makes you wish you had a fisherman’s hover craft.
He caught it right where we are scheduled to have a FAOL Montana Fish-In next year!!! Anyone coming?
With, ah, er, bells on?!

LF, you betcha. Looking forward to it as much as Idaho.

Ditto that Ron. I’ve already got a cabin reserved too.
In my original post on this fly, I included links to Bob Jacklin’s fly and the video of his catch. Just NORTH of this spot, which is located at the end of the road, by the picnic tables…
…it is possible to wade to the far side of the Madison - here. I was not going to try it until I saw a guide take his client through there. I and my two kids fished from that side of the river and it provided some interesting hook-ups…my daughter Ally was the “Whitefish Queen” that day…Shortly before the above photo was taken, a Mama Moose crossed the river in this spot…It shook me up so much that I never got a shot of the critter crossing!!!
Here’s the link:

“My research on this pattern has taken me to one Sandy Pittendrigh, the ADMINISTRATOR at [i]Montana Riverboats[/i] and Willy Self, who guides out of Montana Troutfitters, in Bozeman, MT – a place I have visited on more than one occasion. Sandy is the originator of the above pattern and was influenced by Willy’s use of Lazer Wrap. He has used this fly with success on the Yellowstone River, on Summer mornings. Sandy uses natural Deer Hair for the collar and natural ostrich herl for the thorax…”
Thanks for the pattern Sandy!!!
