Tim Flagler demonstrates how to tie his version of a Crane Fly Larva in this Tightline Productions fly tying video tutorial.
As Tim points out in the video his Crane Fly Larva imitation is a mash-up of Frank Sawyer’s Killer Bug, the Utah Killer Bug from Tenkara Guides, the Jason Klass version of the Utah Killer bug, and Walt’s Worm by Walt Young. Wow! For a simple pattern that’s a lot of mashing!
The secret ingredient in Tim’s Crane Fly pattern is the wool yarn he uses, Jamieson’s Shetland Spindrift Yarn. Jamieson’s is a pure Shetland wool and the Oyster (SP-290) color has a translucent quality when wet that allows the pinkish hue of the yarn to show through just as the Chadwick’s 477 wool yarn used in original Killer bug. This is the property that Frank Sawyer surmised made the original Sawyer Killer Bug so effective. Chadwick’s 477 has not been manufactured in over 40 years and is very difficult and expensive to come by hence the substitution (in case you were wondering.)
