 Graphium agamemnon, Tailed Jay, Green Spotted Triangle, Papilioninae


Native South East Asia   Wingspan 7-8  cm

The female has much longer tails and a distinct greenish white streak on the lower margin of the hind wing. This streak is visible on both sides of the hind wing if examined in hand. In flight, it is difficult to distinguish between the sexes.
The ground colour of the upperside of both sexes is black, and is studded with pale green spots that are a fluorescent green in freshly emerged specimens. The underside is mottled with green, brown, purple and gray.
Although the Tailed Jay spends much of its time in the canopy, it frequently comes down to nectar on small trees, bushes and shrubs, Lanata being one of its favorites. Unlike the Lime Butterfly, it stays away from flowers near the ground. While nectaring, its wings vibrate very rapidly over a small acute angle, allowing it to move at ‘lightning’ speed to the next flower a few inches away.
The males of this species, unlike others in the group, do not visit wet soil or sand. At night, it rests on a leaf with its wings folded up above its abdomen, the forewings slightly pulled inside the hind wings, making it look smaller than it really is.
The first instar larva resembles bird droppings and so can remain safely on the upper surface of leaves in clear view of the predators. Its camouflage is quite impressive to keep the predators deceived. As the larva gets larger, the bird dropping strategy becomes ineffective (after all, bird droppings can get only so big!) and the larva assumes a green colour that blends them well into their surroundings.
