Worm damage is typically identified by which signs?

• A. Streaking on leaves
• B. Irregular holes and chewed foliage
• C. Root dieback
• D. White waxy coating

Answer: (B)

Worm damage shows up as irregular holes and chewed foliage because caterpillars and similar worm pests gnaw through leaf tissue as they feed, leaving uneven bite marks rather than neat patterns or surface coatings. You’ll often notice ragged edges around holes and may see frass (insect droppings) or the worms themselves or their cast skins nearby. Other signs described—streaking on leaves, a white waxy coating, or root dieback—point to different kinds of pests or problems (such as leaf miners or thrips causing streaks, scale or mealybugs producing wax, or below-ground issues causing root decline). In practice, look for chewing damage paired with signs of caterpillars or frass to confirm worm activity.
