Miskimo I found one of these in my pool and then found this http://en.wikipedia.org/wiki/Nematomorph_hairwor
Big Muddy Well this info is well appreciated. I have wondered for many years what the fuck was attached to the large wolf spider my mom found on our porch. Now I know. Thanks!
Another funny thing: My dad said he saw this old boy take a horse hair and leave it in a jar of water and it would turn into a worm. He tried that and it obviously didn't work. Now if someone found a particularly thick horse hair with a worm imbedded this might explain that as well.
