I used to collect butterflies and moths as a kid. I’d spend hours running around our farm in California’s Central Valley, chasing after painted ladies and tiger swallowtails and cabbage butterflies. I’d spend even more (and decidedly less fruitful) hours watching grossly swollen tomato hornworms that I’d placed into mason jars, waiting for them to turn into sphinx moths. But what I liked most of all was poring over websites online where you could select exotic species from around the world and get them delivered, shriveled and dried, to your doorstep. For a price, you could acquire magnificent specimens from all corners of the globe: iridescent morpho butterflies from South America, gigantic golden birdwings from Southeast Asia, and regal emperor moths from Africa.
I though that these mail-order lepidopterans were the closest I would ever get to these far-away places. Then I moved to Zambia 15 years later and discovered that the larval stage of one of these species is a major source of protein for people in my host country during the rainy season. Meet Gonimbrasia belina, whose caterpillar is the tasty snack known locally as ifishimu. More commonly, this winged giant is known as the emperor moth.
