The adults can be found feeding on a variety of flowers.
The origin of Pachliopta is currently unknown. The specie aristolochia is Greek for birthwort.
The Common Rose is primarily found in lowland forest with occasional visits to the surrounding areas.
Males patrol the habitat looking for females. After mating the female searches for host plants to lay her eggs on. The caterpillars feed on the host plant until they form their chrysalis.
During the spring and summer months there are a couple generations in the northern part of their range, while in the south it can be possible to find adults year round.
The Common Rose is considered to be a distasteful butterfly to most predators and displays its colors and pattern to warn predators of its status. One of the female forms of the Common Mormon (Papilio polytes) is even considered to be a mimic of the Common Rose.
