The girls found a caterpillar the other day and brought in to show me. My first thought was grab the bug house and help them find it some food. Within a couple of days it had formed it cocoon. The girls checked it every day several times a day.
Then one day we looked in the morning and it was not open, but by that evening he had emerged. We had a beautiful Monarch butterfly. The kids got to let him loose and they were sad to see him go but knew it was in his best interest.
