How long does a Monarch live?
Butterflies do not have very long lives. Most live for about two weeks. Monarchs can live longer, if they are going to overwinter. (BTW, those that overwinter in Mexico or along the coast of California are NOT the same ones that started their journey! They are usually about the 5th generation that make it to the overwintering site.). Monarchs overwinter as butterflies (not pupa or larva or ova/egg).
