Wooly Worm Or Something Else??

As we were walking the dog this afternoon, we noticed this furry little thing on a tree.  So of course this turned into a science lesson!  My first thought was that it is a wooly worm.  Wooly worms have been thought of to predict whether or not we will have a mild or rough winter.  Supposedly, the more brown on the worm, the milder the winter.  Well, this wooly worm is solid black!  So does that mean we are in for a rough winter??  I just don’t know.  What all do you think??  I would love to hear from you!
