Endless Forms: The Secret World of Wasps

Entomologist Sumner debuts with a tour de force on the world of wasps, delving into their daily lives, economic value to society, and the important ecological niches they fill. Though they have a bad rap, the insects are full of surprises, Sumner writes. For example, they’re the evolutionary precursor of both bees and ants, and their social structures feature “divisions of labour, rebellions and policing, monarchies, leadership contests... negotiators, social parasites, undertakers.” Their genetics open the door to a deep consideration of the evolution of altruism, “one of the longest-standing puzzles in the natural sciences,” Sumner writes, because their willingness to “sacrifice themselves to promote the survival of their relatives” is a central feature of the life of a hive. She recounts their reproductive strategies of paralyzing prey then laying eggs in the bodies, suggests that wasps and bees can recognize individual human faces, and extends her study into a clever calculation of the economic value of wasps, noting that they account for “almost 50 per cent of the 230 invertebrate species that are commercially used as biocontrol agents,” which has an “estimated value of well over $400 billion a year.” Funny, informative, and zippy, this is just the thing for budding entomologists.
