A Yellow and Gray Caterpillar

A reader recently sent us a very direct and simple question. The reader merely sent a picture of what appears to be a caterpillar – it was referred to as a worm, though – and asked what the “worm” was and what it ate. The caterpillar (or what we believe to be a caterpillar) is almost entirely yellow, although it has some gray stripes on it. They aren’t perfectly horizontal stripes, however, as they make more a “v” shape. There are also dozens (if not hundreds) of small black dots on the creature’s back. What is this yellow caterpillar with gray stripes and black dots on its back, if indeed it is a caterpillar at all?
