Which insect is in the order Dermaptera and has simple metamorphosis with chewing mouthparts?

• A. Earwig
• B. Dragonfly
• C. Damsel Bug
• D. European Hornet

Answer: (A)

Earwigs are the insects that fit this description. They belong to Dermaptera and undergo incomplete (simple) metamorphosis, where the young resemble small adults and there is no pupal stage. They also have chewing mouthparts, using their strong mandibles to chew solid food. The other insects are from different orders and have different mouthparts or life cycles, so they don’t match both criteria: dragonflies are in a different order with different wing and life-cycle traits; damsel bugs have piercing-sucking mouthparts; European hornets are in a different order with chewing mouthparts but are not Dermaptera.
