Thanks for this wonderful article. It seems I am always seeing the tobacco/tomato hornworm listed as a serious pest in all of the major gardening publications--and of course, the articles always recommend handpicking and destroying. I have been enchanted with these creatures for many years and often just wait by my phlox in the evening hours--hoping to be graced with the sight of the lovely hummingbird moths. When my daughter was little, they were "fairies" to her. How in the world could I ever bring myself to squash a baby fairy!?! I wish I knew how many times I have told gardening friends to spare them; they are so surprised to learn that the adult form is a lovely and helpful creature. It is reason enough to intentionally plant some "feeder" plants for them.
