An African bugleweed synthesises in its tissues a substance similar to the hormone that controls the development of caterpillars. If a caterpillar is persuaded, experimentally, to ingest that substance, then when it turns into a butterfly it will develop two heads and die. -David Attenborough, The Private Life of Plants, p70
