Graphium evemon eventus
|Common Name:||Blue Jay|
|Extant in countries:||•Singapore|
This species is often confused with Graphium sarpedon luctatius (The Common Bluebottle) when in flight. It can be distinguished from the other species by its black costal bar on the underside of the hindwing, which is united with the dark basal band.
Habitat & Habits
The species flies very rapidly and eratically, and is fond of flying up and down open sunlit jungle paths. The bright blue upperside often shows itself as it flits quickly by an observer. Graphium evemon eventus is a common butterfly in Singapore, and can be seen on most sunny days in the nature reserves.
Only when it stops to feed on roadside seepages, as the specimen featured here was photographed doing, can the observer distinguish it from the more distinctive Common Bluebottle.
