Which order includes katydids and is known for wings held vertically over the body?

• A. Acrididae
• B. Plecoptera
• C. Grylloblattodea
• D. Tettigoniidae

Answer: (D)

Wing position at rest is a practical clue for recognizing katydids. In katydids, the forewings are long and narrow, and they are held so that the wings point up along the body, giving a vertical orientation when the insect is at rest. This upright, vertical-wing posture is a characteristic way katydids present themselves, and they are classified in the family Tettigoniidae within the order that includes other long-horned orthopterans. The other groups show different wing postures: grasshoppers typically hold wings flat over the back or folded along the abdomen, stoneflies rest with wings spread or flat over the body, and Grylloblattodea have highly reduced or absent wings. So the group associated with katydids and this vertical-wing posture is the family Tettigoniidae.
