In the fall, a resident brought us a massive hornworm he had found on a tomato plant in his garden (see photo). Hornworms are the larval (caterpillar) stage of a moth with a wingspan of up to five inches. Despite their prodigious size, hornworms are so expertly camouflaged that they often go unnoticed (by humans). We fed our green giant for a few days, and it methodically munched its way through leaf after leaf of tomato foliage. A few days later, it decided that it had had enough, and began the process of pupation.
