Appias nero are found across India, the Philippines, Singapore, Sumatra, Kalimantan, Sulawesi, Java and Palawan.
   They can be seen in the lowlands, but females are more commonly found at altitudes above 500 m.
   They are often seen in small groups along the riverbanks during March - June.
   They have dark orange dorsal wings.
     When the new butterfly hatches the color is very clear, but the color fades to a pale orange yellow after a few days.
   The male has dark veins on the forewings of the dorsal wings, but not marked, while the females have broad dark borders and a dark subapical stripe on the dorsal wings.
    They have similar wing contours in both sexes with dark orange to brick red dorsal side and pale reddish orange ventral side.
   The male is largely unmarked but has dark scaling along the veins on the dorsal side forewing and along the margin of the hindwing.
   Meanwhile the female has black borders on both wings at dorsal side and black markings on the forewing. They are quite common in inland forest at all elevations but the female prefers high elevations up to 600 m.
   Their estimated lifespan is approximately 14 days.
   They are not considered to be endangered.
