Which of the following insects typically has chewing mouthparts?

Beetles are known for having chewing mouthparts, which they use effectively for a variety of feeding behaviors. This anatomical feature enables them to eat a wide range of plant materials, including leaves, stems, and wood, as well as other insects. The robust structure of chewing mouthparts allows beetles to break down tough plant materials, making them versatile feeders in different ecosystems.

In contrast, moths, flies, and wasps have different types of mouthparts adapted to their feeding habits. Moths generally have siphoning mouthparts designed for drinking nectar from flowers, while flies might possess sponging or piercing mouthparts that allow them to feed on liquids or even to pierce through other surfaces. Wasps typically have chewing mouthparts as well, but their feeding behavior can also include the consumption of liquids, such as nectar, obtained by using their mandibles in a different way. However, the fundamental chewing function is most associated with beetles, which is why they are identified as the correct answer in this context.
