On page 234 Perrault's Std. Dictionary of Fishing Flies I found two
patterns for the Rock Worm. Neither of these were the green version.
Hope this helps.

Met a guy dunking worms with his 8 yr old son, and struck up a
friendship. They were using Colorado meat rigs, i.e. fly rods with
automatic reels and mono line, with split shot and either a crawler or a
rock worm. I gave the little guy some flies which included a scud, and
he proceeded to catch a 3-lb sucker and an almost 5lb carp on the scud.
The night before he caught and landed a 2.7lb brown on a rock worm larva.
