Monarch Butterfly Metamorphosis

Monarch butterfly larvae munch on leaves of a Milkweed plant.  

They move from the Milkweed plants to adjacent vegetation to undergo the amazing metamorphosis into an adult butterfly.  

A larva will first attach its hind end to the stem of a plant with a button of silk, so it can hang head downward. Then the magic happens!  

The larva molts its caterpillar skin and exposes a shiny, green chrysalis (aka pupa) underneath.
