A common species throughout its range. It flies all year round, sometimes in enormous numbers. It can sometimes be found in company with Delias hyparete where their ranges overlap.
Although mainly a species of low altitudes, it has been seen in Myanmar at altitudes up to 7000 feet.
Delias oraia and it's subspecies were, at one time considered to be only subspecies of D.descombesi, but has now been given specific status.
