Herbivory (plant-eating) has evolved repeatedly in insects, typically from meat-eating or detritus-feeding ancestors (detritus is dead organic matter). Moths and butterflies, for example, eat plants. whereas their "sister group" (the insect group to which they are most closely related), the caddisfli
