Question

How is diapause different from hibernation?

Answer 1

In the words of wikipedia again (boy, I'm using it a bit much tonight aren't I?)
"Diapause is not only induced in an organism by specific stimuli or conditions, but once it is initiated, only certain other stimuli are capable of bringing the organism out of diapause. The latter feature is essential in distinguishing diapause as a different phenomenon from other forms of dormancy such as stratification, and hibernation."
