Biology In South Celebes rosenbergi flies all the year round, in large numbers in March and April at the end of the heaviest rainy season. The larva does not differ from that of despoliata from Sumatra, except that it is larger, dark yellow with light yellow and white hairs, and lives on Loranthus, which is parasitical on mango trees. The butterflies first appear very early in the day about 6 or half past 6 o’clock, and then again late in the evening (Martin)Seitz, A., 1912–1927.
