Which term describes the removal of any leaf tissue by an insect with chewing mouthparts?

• A. Defoliation
• B. Skeletonizing
• C. Leafmining
• D. Girdling

Answer: (A)

Defoliation is the broad term for damage where a chewing insect removes leaf tissue or foliage. It captures any situation in which leaf tissue is eaten away, from partial consumption to complete leaf loss. If the insect’s feeding leaves behind only the leaf veins, that pattern is called skeletonizing, which is a more specific form of defoliation. Leafmining involves feeding inside the leaf tissue and creates internal tunnels or blotches, not the external chewing of tissue. Girdling refers to removing a ring of bark around a stem and affects the plant’s vascular system rather than the leaves. So for damage that involves removal of leaf tissue by chewing, defoliation is the appropriate general term.
