Which Orthoptera exhibits simple metamorphosis and chewing mouthparts and is commonly heard chirping?

• A. Field Cricket
• B. Differential Grasshopper
• C. Damsel Bug
• D. Earwig

Answer: (A)

Simple metamorphosis means the young look like small versions of the adults and there is no pupal stage; they molt from juvenile to adult as they grow. Field crickets fit this pattern because their nymphs resemble tiny adults and they undergo several molts before reaching adulthood, all with chewing mouthparts suited for biting and chewing. What really sets them apart here is the chirping sound—males produce a distinctive courtship call by rubbing body parts together, a behavior that’s classic and widely recognized in crickets.

The other options don’t match all parts of the clue. A grasshopper also has chewing mouthparts and undergoes incomplete metamorphosis, but they aren’t known for the iconic, easily heard chirping. A damsel bug is a true bug with piercing-sucking mouthparts, not chewing, and earwigs belong to a different insect order and don’t chirp.
