What classification do beetles fall under?

Beetles are classified as hard-shelled insects because they belong to the order Coleoptera, which is characterized by having a tough exterior known as the elytra that covers and protects their wings and body. This hard shell provides them with protection from predators and environmental hazards, contributing to their survival in various habitats. The unique structure of their body, along with their complete metamorphosis life cycle, distinguishes them from other insect classifications.

Soft-bodied insects typically have a more vulnerable exterior and do not possess the hardened outer shell that beetles do. Wingless insects are those that either never developed wings or lost them over time; however, many beetles do possess wings, which they cover with their hard elytra when at rest. Parasites, on the other hand, refer to organisms that live on or in a host and derive nutrients at the host's expense, which does not accurately describe the ecological role of beetles in most cases. Thus, the classification of beetles as hard-shelled insects is accurate and reflects their biological characteristics.
