It is quite a large and wiggling little bugger....looks to have a tuff of cotton? Hairs? Around what appears to be a stinger of some kind...can hear it audibly scratching the piece of bark it is perched on...it was under the bark of an old black walnut. Bout scared me half to death when I looked down and it was just wiggling away!But I'd love to know if anyone has any idea what it is!
Edit: white stuff reappears after I put some Luke warm water paper towel around it...no idea
