A Very Hungry Caterpillar

We all know the book about the very hungry caterpillar but I feel like I can understand it so much better now. I had a thriving potted tomato plant on my deck that we water every night. One night it was leafy and luscious and then the very next evening when we went out to water it... it looked like thisAll because of two of these lovely or not so lovely caterpillars...

Such a shame...
We tried to net the plant to keep the caterpillars in. We thought since we had lost our tomato plant, at least we could keep him as a science experiment. It seemed only fair. Somehow though both caterpillars escaped. Guess thats life...
