A very hungry caterpillar
This swallowtail caterpillar, steadily chomping its way through milk-parsley, could have crawled out of the pages of the classic children’s book The Very Hungry Caterpillar. First published in 1969, Eric Carle's book has sold nearly 50 million copies since and remains popular with children worldwide.
