Sumner’s book has emerged winged, but it does not quite take to the air. She insists that the 100,000-plus species of wasp — an omnivorous insect that is the ancestor of both the bee (a vegetarian wasp) and the ant (wingless wasp) — are 'genuinely fascinating'. but she spends an inordinate amount of time talking about bees. One feels for her. We love bees. Also, the amount of research by entomologists into bees outnumbers that into wasps by a factor of three, leaving Sumner to lament about wasps: 'We know little.' This is admirably honest, if unsatisfying for a reader.
