Was discussing with LBS today in office about the seasonal appearance of butterflies. we know that most butterflies evolved from eggs to caterpillar ... all the way to adult butterflies. the whole cycle is probably a matter of 3-6 weeks from the egg to the death of adult butterflies.
so the question: where do the butterflies "hide" during the "off-season". do they hibernate? just curious what actually happen during the "off-season".
