Tailed Jay (Graphium agamemnon) lives in tropical rainforest across Nepal, India, Sri Lanka through Southeast Asia and Australia.
Fascinating facts about the Tailed Jay
- Just over one month from egg to adult, the tailed jay can sprint through its life cycle in 33-36 days, then spin out another 13-14 days as a pupa, letting it squeeze up to eight generations into a single year. This rapid turnover fuels its multivoltine habit.
- A single female lays pale-yellow eggs singly on the underside of young leaves, and each egg hatches in just three or four days. The tiny larvae emerge dark yellow-green with a pale band, then molt five times over 15-16 days, growing spiny orange-ringed segments before becoming a clear-green caterpillar. This swift 15-day larval phase is a race against parasitoid wasps that often attack them.
- Tailed jays zip through the canopy like restless drones, constantly fluttering even while feeding. Males sip nectar from bright flowers such as Lantana, Ixora, Mussaenda, and Poinsettia, while females are more often found on host plants or laying eggs. Their nonstop wing beats keep them visible year-round, yet they rarely pause at damp patches, showing a preference for flower nectar over water sources.
- The adult's wings flash a striking green-black pattern: the male's forewing bears a base spot, a short bar, and seven green spots in two rows, while the hindwing adds three transverse green series and a white upper marking in interspace 7. Females mirror this design but add a greenish-white streak along the dorsal margin.
- Once tied to heavy-rainfall woodlands, the tailed jay now thrives in low-elevation gardens.
