I think this is some sort of spider ???? You could put 4 of these fellows on a dime. From above it looks like a little cotton ball. It appears to be its outer cover and camouflage from other predators. Found outside my house in Tupelo,MS. USA.
See in comments for Description by John Lenagan about this creature. Thank you John :O)
