The giant swallowtail is the largest island butterfly at 4-5 inches. They have yellow spots at the bottom of the hindwings, and yellow on the tops of the wings makes a cross near the edges. They have blue and maroon spots as well. They lay their eggs on the toothache tree and feed on seashore mallow.
