Delias oraia is a butterfly in the family Pieridae. It was described by William Doherty in 1891. It is found in the Australasian realm.
Original A local form of the Indian Delias descombesi, and greatly resembling it. It lacks, however, the black marginal band of descombesii, the costa and outer margin of both wings being slenderly grey, especially at the ends of the veins, the cilia lemon. Below the five subapical lunules on the forewing are yellow, not white. The female is generally brighter coloured than that of descombesii. The hindwing, however, is much darker over the base and disc, but below the submarginal spots are bright lemon, and the hind-margin rich ochreous. Sambawa, 2âÂÂ5000 feet, scarce.

It is a member of the belisama group which includes
