Troidini

Troidini is a tribe of swallowtail butterflies that consists of some 135 species in 12 genera. Members of this tribe are superlatively large among butterflies (in terms of both wingspan and surface area) and are often strikingly coloured.

Genera
The tribe consists of the following genera:


 * Atrophaneura
 * Battus
 * Byasa
 * Cressida
 * Euryades
 * Losaria
 * Ornithoptera
 * Pachliopta
 * Parides
 * Pharmacophagus
 * Trogonoptera
 * Troides

Ecology
Members of this tribe feed on poisonous pipevine plants, typically of the genus Aristolochia, as larvae. As a result, they themselves are poisonous and unpalatable to predators (Pinheiro 1986), like the pipevine swallowtail, and are mimicked by other butterflies (Scott 1986).
