Which insect has complete metamorphosis and belongs to Diptera?

• A. Fruit Fly
• B. German Cockroach
• C. Giant Water Bug
• D. Green Lacewing

Answer: (A)

This question tests whether an insect both belongs to Diptera (the true flies) and undergoes complete metamorphosis. A fruit fly is a small fly in Diptera and, like other flies, experiences four life stages: egg, larva, pupa, and adult. That full transformation is what complete metamorphosis means. The other insects don’t meet both criteria: German cockroaches are Blattodea and show incomplete metamorphosis with nymphs resembling small adults; giant water bugs are Hemiptera with incomplete metamorphosis; green lacewings are Neuroptera and also have complete metamorphosis, but they are not Diptera.
