The eastern long-eared bat uses torpor during winter and is able to arouse and forage during warm periods. [25] Some animals use torpor during their reproductive cycle, as seen in unpredictable habitats. [24] They experience the cost of a prolonged reproduction period but the payoff is survival to be able to reproduce at all. [24]

One example is the mourning cloak butterfly, which experiences advantages to overwintering in its desired locations by being one of the first butterflies to emerge after a cold winter. [2] Another example are the eggs of the forest tent caterpillar moth which overwinter tightly packed on tree branches. [3]

Some animals "sleep" during winter and only come out when the warm weather returns; e.g., gophers, frogs, snakes, and bats.
