Hook - Any straight shank streamer hook. I tied the ones for this sway on a TMC 5263 size 6 as I like the 3x long shank and 2x heavy wire.
Thread - UTC 140 matching color
Tail - Olive barred rabbit strip.
Body - olive cactus chenille with remaining tail strip tied over the top (think zonker fly)
Head/thorax -EP Tarantula Hairy Legs Brush 1" Wide Sculpin.
There are so many options with this pattern! You can tie them weightless, like the swap flies are, or you can weight them with lead wraps or eyes.
You can add gills, fins, etc...
For a fantastic crayfish pattern, simple tie in some lead eyes at the hook eye and use 2 rabbit strips as the claws.
