Eggs and Larvae
Female monarchs are laying eggs of the 2nd generation now. These monarchs will be the grandchildren of butterflies that overwintered in Mexico. Monarch generations are continuing the cycle. It takes about one month for each to develop. Over the summer, three generations will be produced in the north.
