Mysterious chrysalis

Over the years when digging in the soil i have found red shiny chrysalis, when they are held in the hand they wiggle.  I have often wondered what would hatch out of them.  I found one recently and popped it into a container and waited.  It hatched into a moth called a Yellow underwing.  The moth itself  looks brown when resting but once it flies it displays a yellow underwing.
