Pipevine swallowtail chrysalis. Chrysalis of the pipevine swallowtail butterfly (Battus philenor) on a plant stem. A chrysalis is formed when a caterpillar is ready to undergo metamorphosis into an adult butterfly. The caterpillar's organs degenerate completely and a new body develops. Pipevine swallowtail caterpillars and butterflies are toxic to predators. They gain the toxic chemicals from the pipevine plant (Arustolochia sp.) on which they feed. These butterflies are usually found from the southern United States to southern Mexico. Photographed in Dallas County, Texas, USA.
