Which order is known for ambush predation and unusual mating, including potential male decapitation or being eaten during courtship?

• A. Isoptera
• B. Mantodea
• C. Grylloblattodea
• D. Plecoptera

Answer: (B)

The main idea here is the combination of an ambush predation strategy and unusual mating behavior seen in mantises. Mantodea are classic ambush predators: they sit camouflaged and wait for prey, using their fast, spiny forelegs to grab it in a single strike. In mating, they exhibit an extreme behavior that has captured attention—sexual cannibalism, where the female may attack and eat the male during or around courtship. In some cases, the male is decapitated during the encounter, yet copulation or sperm transfer can still proceed. This striking pairing of stealthy predation and potential aggressive mating makes mantises the best fit among the options. The other groups are not typically linked with this combination; termites are social, wood-eaters; Grylloblattodea are rare, cold-adapted insects; stoneflies have aquatic larvae and different mating behaviors.
