They metamorphose into a really neat looking huge, night-flying moth.
These caterpillars of the night-flying moths eat the leaves of one of my shade trees. (I have yet to find them on my tomatoes or other plants.) My big pitbull-mastiff dog that isn't afraid of anyone or anything is afraid of those caterpillars when they fall off the tree and unto the ground near his dog house. He barks like mad over that caterpillar.
