Tropical swallowtails are a species of moth found in a wide variety of locations across Asia, primarily Southeast Asia. Colors of the species range from light brown to black with white and muted purple markings. They have a tendency to engage in swarming behavior, though it may not be true swarming and could be linked to mass emergence from weather conditions and low predator rates. When resting, the tropical swallowtail will turn upside to draw attention away from its body and towards its hind wing tails. These moths are also known by the name, “Laos brown butterfly”, though they scientifically are not butterflies.
