Thought about going the Peter Brigg spider route but ended up sticking with a foam rubber legs pattern. These have been tied onto a #8 14731 Caddis Larva Grip hook. I added some dubbing for the under body purely as a base to give the foam something to bind to. Strapped a small piece of light brown foam on. Added 4 rubber legs. Positioned them how I wanted then added a tiny piece of yellow foam for an indicator....sorted!!
They float exactly how I was hoping they would. I'm not too worried if the rubber legs move around with the rivers current that much as I'm hoping they will give off much needed subtle vibrations giving the impression the spider is struggling to stay a float. I have a good feeling about these little wolf Spiders come January up in Lesotho.
