Jet black butterfly with row of white spots along the middle part of hindwing. 90–100 mm.
The Common Mormon prefers lightly wooded country, but is present everywhere and high up into the hills. It is a regular visitor to gardens, being especially abundant in orchards of its foodplants - oranges and limes. It is most common in the monsoon and post-monsoon months.
In India, this butterfly is considered as the classic example of Batesian Mimicry in which edible species resemble unpalatable butterflies in order to escape being eaten by predators.
