What is the difference in the use of mimicry between katydids and crab spiders?

• A. Katydids use mimicry to ambush prey.
• B. Crab spiders use mimicry to hide from predators.
• C. Katydids use mimicry to hide from predators.
• D. Both use mimicry to attract mates.

Answer: (C)

Mimicry is a pattern of resemblance that helps an organism either avoid being noticed or catch prey. Katydids often imitate leaves or twigs, staying very still so they blend into the foliage. This camouflage mainly serves to protect them by making predators fail to notice them. Crab spiders, by contrast, blend in with flowers, which lets them lie in wait for visiting pollinators. Their mimicry is used to capture prey rather than to avoid predators. So the difference is that katydids use mimicry to hide from predators, while crab spiders use it to ambush prey. The other ideas don’t fit because katydids aren’t primarily using mimicry to ambush prey, and crab spiders aren’t mainly hiding from predators; they’re using camouflage to prey on visitors.
