Footmen, whose populations are on the march as their lichen food recovers from decades of industrial pollution. The Goat Moth, a thumb-sized broken stick mimic, that takes several years to mature deep in the wood of tree trunks. The Oak Eggar, with the look of a bemused Honey Monster, host to a large wasp that eats its caterpillars alive from the inside. The Uncertain, whose similarity to other species has motivated its English name. The Silver Y, with a weight measured in milligrams, but capable of migrating across a continent. A moth trap is a magical contraption, conjuring these and hundreds of other insect jewels out of the darkness.

In THE JEWEL BOX, he reflects on what he has learned in thirty years of work as a scientist studying ecosystems, and demonstrates how the contents of one small box can illuminate the workings of all nature.
