Which of the following is an example of a destructive insect?

Beetles are considered an example of a destructive insect because many species feed on plants, crops, and other vegetation, potentially causing significant harm to agricultural and horticultural interests. Certain beetles, like root weevils and Japanese beetles, are notorious for their ability to damage roots, leaves, and even fruit. Their feeding habits can lead to reduced plant health, diminished crop yields, and economic loss for farmers and gardeners. In contrast, butterflies, ladybugs, and pollinating bees play more beneficial roles in the ecosystem, such as pollination and pest control, which are crucial for plant reproduction and maintaining ecological balance.
