The Common Jay is a swift flyer and is quite commonly found together with the Common Bluebottle, Graphium sarpedon. However, there are a few distinctive species of Common Jays that are difficult to tell apart unless close scrutiny is given to the markings on their undersides...
Graphium euryplus mecisteus (Distant)
Graphium doson evemonides (Honrath). In comparison to Graphium euryplus, notice that the black coastal bar is NOT united to the dark basal band on its hindwing.
Graphium evemon eventus (Fruhstorfer). Compare to the two precedents, this one does not have a red spot on its coastal area on the hindwings.
Graphium chironides malayanum (Eliot). This one also does not have a red spot on the coastal area of the hindwings but has a black bar that run through the vein 6. Notice that the red spots are replaced by faint orange spots that are narrower.
Graphium bathycles bathycloides (Honrath). This species has narrower blue spots on the forewings and a yellowish base on the hindwings in comparison to G. chironides and does not have the distinctive white spot on the base of space 3 on its hindwing.

I have to confess that it's difficult for me to tell G.doson and G. evemon apart, but what you have here is a great guide to the complex.
