NOT typically found in the head region of many insects?

• A. Antennae
• B. Compound eye
• C. Mandibles
• D. Walking legs

Answer: (D)

Insects have three main body regions: head, thorax, and abdomen. The head houses sensory and feeding structures, including antennae for smell and touch, compound eyes for vision, and mouthparts like mandibles for biting and chewing. Walking legs, however, are attached to the thorax—the middle region of the body—so they are not found on the head. That’s why walking legs are not typically found in the head region. This layout—head with sensory and mouthparts, thorax with legs (and often wings), abdomen as the posterior division—is a standard feature of insect anatomy.
