What visual indicators suggest feeding by chewing insects?

Holes and jagged edges in leaves are definitive signs of feeding by chewing insects. These insects, such as caterpillars, beetles, and certain types of grasshoppers, utilize their strong mouthparts to bite and consume the leaf material. The damage manifests as holes or irregularly shaped edges along the leaves, providing clear visual evidence of their feeding behavior. This distinctive pattern is unlike other forms of insect damage, such as the stippling caused by sucking insects or webbing produced by spider mites, making it essential to identify the type of damage to implement effective pest control measures.
