Surplus Fly (Flower Fly) belongs to which order?

• A. Hymenoptera
• B. Lepidoptera
• C. Diptera
• D. Coleoptera

Answer: (C)

Understanding how to identify insect orders by wing structure helps with placing flower flies in the right group. Flower flies are true flies, which puts them in the order Diptera. The key feature of Diptera is having a single pair of wings; the second pair is reduced to small balancing organs called halteres that aid in stable flight. This distinguishes them from other orders: Hymenoptera includes bees, wasps, and ants with typically two pairs of wings and often a narrow waist; Lepidoptera includes butterflies and moths with scaly wings; Coleoptera includes beetles with their forewings hardened into protective elytra. So, the Surplus Fly belongs to Diptera.
