Estaz Bug
Note: This is a good pattern. It imitates nothing natural, but does a fair imitation of a Mr. Twister Grub. I have caught everything from Snapper Blues to Trout on it. My biggest fly rod smallmouth, 18 inches, fell for a size 4 white one.
A very simple tie. Wrap your lead wire around the shank. Tie in sparse amount of flash material(about 10 strands) then tie in your marabou or arctic fox. Tie in the estaz, wrap forward and tie off, build a thread head. Now take your scissors and trim, give it a crew cut. It should have a grub shape when done.
How to fish. I have caught fish dead drifting it, I have had them pick up as it was lying on the bottom, or when stripped in.
