Welcome to the website about the wonderful Delias butterflies !
The reference website about Delias butterflies
On this website, you will find up-to-date information about the Delias butterflies of the world. The butterflies which make up the Pierine Genus Delias are to be found in Central and Southern China, Tibet, Taiwan, India eastwards to the Solomon Islands and Australia, although the 'hotbed' is the Island of New Guinea (West Papua & Papua New Guinea).
These butterflies frequent grass country and open woodland. They generally occur from 2500 to 8000 feet, and very occasionally to 10000 feet. Because of this habit of only living in mountainous areas, where populations are isolated, many distinct subspecies have been found, unique to a single mountain range.
Those species which have the widest range are those which can be found at lower altitudes.
