I love a well-named insect; there is no doubt about what the grapeleaf skeletonizer moth (Harrisina americana) eats and what economic impact it might have. Fortunately, I do not have any grape vines, so I can just enjoy this strangely-shaped little black and red moth. (It does eat other things, but I have plenty of plants available, enough to share with a few caterpillars.)

The larvae are black and yellow, and really do terrible things to grape vines. Adults feed on nectar.
