What are Caterpillars?
Caterpillars are the larvae of butterflies and moths. Many species cause damage to all different types of crops, using their powerful jaws to nibble leaves back and forth. They are usually inconspicuous and can be very hard to find on plants, as they blend in being green, brown, and grey. They also eat almost uninterruptedly, except when moulting.
Caterpillars can cause serious economic damage. Most species feed on leaves and young shoots, rapidly decimating a plant. Leaves will be skeletonized, with only the mid-rib intact and they will spoil the plant by leaving large quantities of frass behind.
