Indian tortoiseshell

This tortoiseshell survives winter as a hibernating adult at high elevation, then reappears on the wing as soon as the mountain slopes begin to warm.

The Indian tortoiseshell has pale brown and yellow forewings and red-tinged hindwings, its underside closely set with short dark transverse streaks and crossed by a sinuous pale blue band near the margin.

It flies over mountain meadows and forest edges at elevations from about 600 to 5500 metres, basking on bare ground or rock and overwintering as an adult through the coldest months.
