At last we have an eyewitness photograph of the vicious fence lizard! (Thanks Gudrun) Note the yellowjacket held helpless in the predator's powerful jaws.
In some cultures, a traditional test of adulthood is for a young person to plunge their bare hand into a large jar filled with multi-colored gumballs and a single hungry fence lizard lurking at the bottom.
You see a lot of three-fingered kids in those cultures.
(Okay, I made the last part up. The lizard usually kills and eats them.)
