The harvester (Feniseca tarquinius) is our only carnivorous butterfly. No, I’m serious. Dead serious. As a caterpillar, the harvester preys on other insects: certain wooly aphids. As an adult, it ignores flowers and only drinks honeydew, a sugary substance secreted by those aphids. Tiny, voracious, adorable - why isn’t there a harvester movie? I’d watch it in 3D.
