Caterpillars are the juvenile stage of butterflies and moths and chew into plant tissue. They commonly feed on foliage, young stems and buds. They vary in colour and size according to the species and most are great at hiding from hungry predators so they’re not always easy to find. However they have enormous appetites and can devour large sections of a plant very quickly so you’ll certainly see the damage. Another telltale sign of a caterpillar attack is often you’ll see their droppings left on lower leaves.
All plants are vulnerable.
