This little fuzzy caterpillar may look harmless, but beware. Those fuzzy "hairs" sting!! Sam learned the hard way, he got stung all over his fingers and it is very itchy!! Dumb mom thought it would be cool to take a picture of the caterpillar who had just come out of the larvae stage. I encouraged Sam and his friends to play and build a habitat for them. Well, the caterpillar obviously did not appreciate it and he got even. Poor Sam!
