What do caterpillars feed on?
Caterpillars feed on specific plants that we refer to as their host plants. Each species of butterflies have their own particular host plants. For example, Monarch caterpillars feed only on Milkweeds. Most caterpillars feed on leaves, but some will also eat the flowers and seeds. The Harverster butterfly caterpillar actually feeds on aphids; it is thought to be the only carnivorous butterfly larva.
