James W. Truman

The process by which a butterfly emerges from a chrysalis, called ecdysis, has been thought to be controlled by eclosion hormone. J. Truman discusses the discovery of a new insect hormone, reported in this issue of Science by hacek Zithacek nan et al. (p. 88), that can also trigger ecdysis--MasETH. The two hormones seem to act sequentially.
