We found some specimens of Aporia signiana Sugiyama, 1994 in our collection. The hind-wing underside was dusted with a lot of black scales. After detailed observation, we find that A. signiana has wide color variations in hind-wing underside, from whitish color to blackened dark color, which is considered as a distinct characteristic of this butterfly.
