The Chequered Swallowtail Butterfly (Papilio demoleus), unlike most swallowtail butterflies, does not have a prominent tail. The species Papilio demoleus occurs as a number of subspecies over much of tropical Asia. The subspecies Papilio demoleus sthenelus is found across the mainland of Australia and New Guinea.

Like most swallowtail species, they usually feed from flowers while on the wing. They are often seen in a group, especially at the edges of water sources on a hot day. They imbibe the water up through their proboscis, remove any water soluble nutrients in their stomach, then squirt out the remaining water from their rear ends.

Common name
Lime Butterfly, Lemon Butterfly, Lime Swallowtail, Chequered Swallowtail. In many instances, the common names refers to the host plants they are seen on.
