Which insect has Diptera and complete metamorphosis and mouthparts Sucking?

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

Answer: (A)

Recognizing Diptera, the two-winged flies, and their holometabolous development helps identify the insect. Among the options, the fruit fly is the only true fly, so it fits as a Diptera that undergoes complete metamorphosis. The green lacewing is holometabolous but from a different order and has chewing mouthparts. The German cockroach isn’t a fly and doesn’t undergo complete metamorphosis. The giant water bug is a true bug with piercing-sucking mouthparts and an incomplete metamorphosis. Therefore, the fruit fly best fits all the described traits: Diptera, complete metamorphosis, and mouthparts suited for sucking liquids from fruit.
