Which species belongs to order Orthoptera and has Simple metamorphosis?

• A. Red-Legged Grasshopper
• B. Saw-Toothed Grain Beetle
• C. Robber Fly
• D. Praying Mantis

Answer: (A)

Understanding which insects belong to Orthoptera and how they develop helps identify the correct species. In Orthoptera, development is simple metamorphosis: eggs hatch into nymphs that resemble miniature adults, with no pupal stage.

The Red-Legged Grasshopper fits both criteria: it’s a grasshopper, an obvious Orthoptera, and its life cycle goes from egg to nymph to adult, with nymphs that look like smaller adults.

The other options don’t match both criteria. Saw-Toothed Grain Beetle is a beetle (Coleoptera) and undergoes complete metamorphosis, with distinct larval and pupal stages. Robber Fly is a fly (Diptera) and also undergoes complete metamorphosis. Praying Mantis is in a different order (Mantodea) and, while it has incomplete metamorphosis, it’s not Orthoptera.
