Yellow Caterpillars with Black Stripes

A little while ago, we received a question from a reader asking about a worm he found near his garden. It is primarily yellow, but it has small black stripes on it too. The reader found this yellow creature with black stripes, which is shaped like small tube, on a tree. He sent a nice picture of the worm (which is in fact probably a caterpillar), which is below. He was wondering what kind of worm he found, and also if it was “aregetic” to humans. “Aregetic” is not a word, as far as we and Google can tell, so we suspect the reader might have meant something like “harmful” or “dangerous,” as this is the most common concern that readers have with worms (or caterpillars) they find. What is this worm or caterpillar, and is it dangerous?
