On a balmy January morning in Manaus, a Brazilian port city surrounded by rainforest, a group of entomologists and I scattered into a supermarket to stock up for an expedition.
Twenty minutes later, in the checkout line, it became clear that we had different ideas about what that meant.
I had peanuts, raisins, and bug repellent; the entomologists, all of whom were dipterists, or fly specialists, had heaps of bruised produce, nearly expired trays of chicken, and bits of peacock bass wrapped in cellophane.
