Graphium agamemnon, the tailed jay, is a predominantly green and black tropical butterfly that belongs to the swallowtail family. The butterfly is also called the green-spotted triangle, tailed green jay, or green triangle. It is a common, non-threatened species native to Nepal, India, Sri Lanka through Southeast Asia and Australia. Several geographic races are recognized. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Strong and restless fliers, they are very active butterflies and flutter their wings constantly even when at flowers. They are seldom seen drinking from damp patches. The males are particularly fond of nectaring from flowers such as Lantana, Ixora, Mussaenda, and Poinsettia. The females are more likely caught when looking for food plants or laying eggs.
Tailed jays are active throughout the year but their abundance depends upon the local monsoon and availability of the larval host plants. The butterflies generally fly among the tree-tops but descend to ground level in search of flowers or host plants. Because of their relatively fast life cycle (just over one month from egg to adult), tailed jays are multivoltine and may produce up to seven or eight broods per year. It has been noted in one instance to be attracted to lights at night.
