This butterfly’s wingspan is between 6.7 and 8 cm. It has yellow wings with black stripes and black edges. Blue, yellow and orange spots can be seen along the border of its back wings. There is a yellow stripe all along the border of its back wings.
This butterfly’s wingspan is between 9 and 10 cm. Its black wings have two rows of yellow spots along the edges. The lower wings have an orange spot with a black centre on the bottom edge, and the tip of the wing is long and thin.
Females can be distinguished from males by their larger abdomens and a wide band of blue scales on their back wings. The two rows of yellow spots are less pronounced in females.
In most species of Papilionidae (swallowtail butterflies), the back wings have a long tip at the end that looks like a swallow’s tail. Most swallowtail caterpillars have an osmeterium, an organ with two small horns that produces a foul odour. Some have large eyespots that can frighten predators.
