We were excited when we found the Black Swallowtail Caterpillar so imagine how we felt when we realized we had a Giant Swallowtail Caterpillar too. By the time two more days had passed we realized we had at least five Giant Swallowtail Caterpillars. We are looking for more. They are supposed to be rare in our area.
Below are some close ups of some of the patterns on the caterpillars.
