Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
A lime is a citrus fruit, which is typically round, green in color, 3–6 centimetres (1.2–2.4 in) in diameter, and contains acidic juice vesicles.

Goodenough Island in the Solomon Sea, also known as Nidula Island, is the westernmost of the three large islands of the D'Entrecasteaux Islands in Milne Bay Province of Papua New Guinea. It lies to the east of mainland New Guinea and southwest of the Trobriand Islands. It is roughly circular in shape, measuring 39 by 26 kilometres with an area of 687 square kilometres (265 sq mi) and a shoreline of 116 kilometres (72 mi). From a coastal belt varying in width from 2 to 10 kilometres in width, the island rises sharply to the summit of Mount Vineuo, 2,536 metres (8,320 ft) above sea level, making it one of the most precipitous islands in the world. The small outlier Wagifa Island lies to the south-east of the island, and is included within Goodenough's administration.
Papilio demoleus is a common and widespread swallowtail butterfly. The butterfly is also known as the lime butterfly, lemon butterfly, lime swallowtail, and chequered swallowtail. These common names refer to their host plants, which are usually citrus species such as the cultivated lime. Unlike most swallowtail butterflies, it does not have a prominent tail. When the adult stage is taken into consideration, the lime swallowtail is the shortest-lived butterfly, with male adults dying after four days and females after a week. The butterfly is native to Asia and Australia, and can be considered an invasive pest in other parts of the world. The butterfly has spread to Hispaniola island in the Western Hemisphere, and to Mahé, Seychelles.
