Jumping insects like grasshoppers, crickets, and katydids are in which order?

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

Answer: (B)

Jumping insects like grasshoppers, crickets, and katydids belong to the order Orthoptera because their hind legs are specially adapted for powerful jumps (saltatorial legs), which is a defining feature of this group. They also typically have chewing mouthparts and front wings that are tough and leathery (tegmina) with hind wings that are membranous and folded underneath, traits commonly seen in orthopterans. Some species also produce sound by rubbing parts of their wings or legs, a behavior often associated with Orthoptera. In contrast, Diptera are true flies with a single pair of wings and halteres; Hymenoptera (bees, wasps, ants) usually have a constricted waist and different wing/body structure; Lepidoptera (butterflies and moths) have scaled wings and a coiled proboscis. So the jumping insects listed are categorized in Orthoptera.
