Before and After: A Monarch’s First Day as a Butterfly

This before-and-after image shows a monarch newly emerged from its chrysalis. The photos are only two hours apart in time. The monarch's wings in the after shot are still small and weak. Monarchs generally need to hold onto their chrysalises for at least two hours after first emerging, waiting for fluid to pump into their wings and make them strong enough to fly.
