Of course if you have an garden you will have bugs. Lemony found a very large caterpillar eating the tops of the carrots one day. After much debate if we should squish him or not (I thought it was probably just going to eat everything and turn into a tree-destroying moth), our daughter fairyberry came to the rescue with her butterfly book. We think it is an Eastern Black Swallow Tail, and with a little research, found that it was the second easiest caterpillar to raise in captivity. So he was named, housed and fed all the carrot tops and parsley he could eat.
Below is a closeup of the caterpillar, a little blurry through the glass. He was green with black strips and yellow dots.
So we fed the bug and waited. A few days latter it attached to a stick we had placed in the bowl and hung like a J. The next morning the brown, woody looking chrysalis had formed. A little over a week latter my wife came home to find this in the bowl.
Lemony took this picture and released the butterfly in the yard. He flew away over the neighbors house. I have to admit, I am happy no one listened to me and we did not squish the caterpillar.
Update from Lemony: Turns out that Heimlich is a girl.
