Many years ago, I was a volunteer moth-hunter. I wasn’t a collector (I’ve always been puzzled by the impulse to capture a live creature, gas it and then pin its motionless corpse to a board); I was just another helping hand for a number of surveys aimed at estimating the variety and size of local populations. At the same time, I was working at one of Cambridge University’s zoology field stations, an idyllic smallholding just off the Huntingdon Road, where my boss, Gerry, bred cockroaches, locusts, tobacco moths and other insects for study purposes.
I was the merest factotum at that facility, a rather feckless boy taken on to tend the gardens and glasshouses, but Gerry did his best to include me in the more interesting work, including his daily, highly security-conscious visits to the tobacco moths, which were kept under dark netting in a double-walled building within the complex.
