Eastern Tiger Swallowtail

papilio glaucus


Tiger Swallowtail caterpillar, about two inches long, in a defensive stance swelling up and showing off eye-spots to attempt to ward off predators.


Found in an urban area.


We found this caterpillar crawling through our newly planted butterfly garden along the side of the house, even though none of the plants there are ones it would feed on as a host plant.
