Do moths cause damage to plants once they reach adulthood?

• A. Yes
• B. No
• C. Only at night
• D. Only in winter

Answer: (B)

The main idea is that plant damage from moths comes from the larval stage, not the adult. Adult moths typically don’t harm plants because their mouthparts are usually adapted for sipping nectar, not chewing leaves or boring into stems. The real feeding and resulting damage come from caterpillars (the larvae) that chew on leaves, buds, or fruit or bore into plant tissue. So, in gardens or landscapes, you’d look for signs of eggs or caterpillars rather than damage caused by adults. That’s why the statement is that adults do not damage plants in the usual sense. The other options mislead by implying damage happens due to adult activity at night or only in winter, which isn’t how moth damage typically occurs, and they don’t reflect the actual feeding pattern of moths.
