Aglais caschmirensis is a butterfly found in the
northern regions of the Indian subcontinent, primarily in the Himalayas (Kashmir to Sikkim) at elevations of 600 to 5,500m. (2,000 to 18,000 ft).
   They are active from the beginning of their summer in March untill the ending of their autumn November.
   As winter approaches with chilling cold and snow, they hibernate from December to the end of February in farmyard buildings, nearby house sheds, sheltered structures, garages or inside tree hollows, log piles and even rock crevices. 
   They remain inactive during the months from December to February, when cold grips the entire Himalayan region during the winter
   The life cycle of the Indian Tortoiseshell, which is comprised of the egg stage, followed by 5 larval stages, pupal and adult stages depending upon the climatic conditions, is completed in 31 to 44 days.
   As the adults fly from flower to flower to take nectar, pollen is inadvertently collected on their bodies, to be left on other flowers they visit, thus continuing the pollination process.
   The Indian Tortoiseshell has the ability when threatened by potential predators, to emit a hissing sound by rapidly vibrating their wings, thus deterring the would be predators.
