Common Tiger Butterfly

<em>Danaus genutia</em>, known as the common tiger butterfly, is a striking medium-sized butterfly in the family Nymphalidae, closely related to the well-known monarch butterfly. It is widely distributed across South Asia, Southeast Asia, and parts of Australia, occurring in countries including India, Sri Lanka, Thailand, Malaysia, Indonesia, and the Philippines. This species typically inhabits forest margins, gardens, grasslands, and secondary growth areas, where it can be found nectaring on a wide variety of flowering plants. The wings are characteristically orange-brown with bold black veining and white spots along the margins, providing effective warning coloration that signals its chemical unpalatability to potential predators. Like other danaid butterflies, <em>Danaus genutia</em> sequesters toxic cardenolides from its larval host plants in the milkweed family (Apocynaceae), making adults distasteful to most birds. Larvae feed on various species of Cynanchum, Tylophora, and other Apocynaceae members. The species is currently listed as Least Concern by the IUCN, and its populations are generally considered stable owing to its broad habitat tolerance and wide geographic range. Biological traits such as average lifespan, body measurements, and weight remain poorly documented for this species in the scientific literature.
