Red-striped Worms with Horns are Leafy Spurge Hawk Moth Caterpillars

“Are you able to identify these?” is all Carol asks in her submission regarding the beautiful, black worm-like critters pictured below. This is definitely one of the best photos we have received in a while. It captures in such detail the unique appearance of these creatures: their pattern of white polka dots and yellow markings, the long red stripe that runs the length of its back, and the horn sticking out from the rear end of its body. Typically, it is still difficult to identify some organisms without more context, even if the photo is good, but this photo is so clear that we managed to identify these guys with no context. These are leafy spurge hawk moth caterpillars!
