Papilio arcturus is rare in montane forests at moderate to high elevations (Alt. 530 - 2500m). Both sexes visit flowers. Males form flight paths along streams or forest edges and frequently come to the banks of streams and puddles to suck water, and are territorial on hilltops.

Papilio polytes is very common in secondary forests at low to moderate elevations (Alt. 10 - 1300m) and it is often seen in urban areas. Both sexes visit flowers. Males form flight paths along streams or forest edges. Both males and females are highly variable in their markings, especially females, which are polymorphic and mimic various Byasa and Atrophaneura species.

P.arcturus flies in May and P.polytes can be seen year-round.
