The copperhead crab Is a fly I designed a few years ago… we sell them now… but here is the formula if you wanna try blind:
Hook: Gamakatsu SC15 - #1 - 1/0
Eyes: Med plain lead
Body: Gold or copper small mylar tubing
Tail: splayed hackles in amber or brown
Copper flashabou
Legs: Crazy legs - Tan, Copperhead, rootbeer
Instructions:
1.) Start thread very close to the eye of the hook and secure in the lead eyes ( you don’t want much space at the front of the hook, just enough to tie in a weed guard.)
2.) Move to the back of the shank and tie in a clump of flashabou approx 3/4" to 1" long.
3.) Choose two hackles and splay them on either side of the flashabou… the hackles should be curving away from one another.
4.) Now take the mylar and cut a section about 2" long. Remove the cotton string from the core, and tie in just in front of the tail figue eight style so that the mylar is lying perpendicular to the hook shank . (do this the same way you would tie in yarn on any other crab pattern)
5.) tie a strand of crazy legs close in front of the mylar so that it extends about 2" on either side… you want long stringy legs.
6.) Continue alternating the mylar and crazy legs until you have filled the shank up against the lead eyes.
7.) Now tie in your weed guard… I prefer a double strand mono guard tied right in front of the lead eyes… but any guard you like will work here.
8.) Whip finish and coat head and body wraps with head cement to secure the wraps.
9.) Once the fly has dried remove it from the vise… pull the rubber legs away from the body and trim the mylar tubing into a round crab shape… Once you have it trimmed flare the mylar by rubbing it with your fingers so that it all unravles into a bushy body…
This fly is great for fishing in thick grass… I call it my combat fly… Don’t strip it, just pick out the fishes direction, put it in his way, and when he gets near it just wiggle it a little… he will find it!
Good luck out there!
