Question: 1 / 400

Which classification describes the Colorado potato beetle's mouthparts?

Chewing

The classification of the Colorado potato beetle's mouthparts as chewing is accurate because these beetles possess mandibles that are specifically adapted for biting and grinding plant material. This adaptation allows them to effectively feed on the leaves of potato plants and other solanaceous crops. Chewing mouthparts are a characteristic feature of many insects that consume solid food, particularly herbivores, making it suitable for the Colorado potato beetle, which primarily feeds on foliage.

Understanding this classification highlights the ecological role of the Colorado potato beetle as a pest in agriculture since its chewing mouthparts allow it to damage crops significantly, leading to economic losses for farmers. Other mouthpart types, such as piercing-sucking or cutting sponging, are adapted for different feeding strategies that do not apply to this beetle's feeding habits.
