Four-Bar Swallowtail Butterfly

Ironically, because the four-bar swallowtail butterfly has an extremely short adult lifespan and only produces a single brood per year, the species was not officially included in the modern faunal lists of China until 1994. However, human population growth, commercial exploitation, and forest destruction had already begun shrinking the crucial habitats of the species. In Cambodia and Laos, the ephemeral four-bar swallowtail butterfly is considered an endangered species.
