The larva of the black swallowtail first looks like a tiny black ant, and it will not move for the first few days. It will get a white strip in the center of it. When I first saw one I thought it was bird doo-doo! It kind of looks like it.
You'll see several color changes in the black swallowtail larva. When it matures, it looks a lot like the Monarch larva. They have pretty much the same colors, but the pattern is different. They are really pretty!
