The jewel box

Every morning, ecologist Tim Blackburn is inspired by the diversity contained within the moth trap he runs on his roof. Beautiful and ineffably mysterious, these moths offer a glimpse into a larger order, one that extends beyond individual species and into a hidden landscape. 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. 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.
