What is the primary purpose of mimicry in katydids?

• A. To attract mates
• B. To regulate body temperature
• C. To hide from predators
• D. To communicate with humans

Answer: (C)

Mimicry in katydids works as a defense through camouflage. Many katydids have leaf- or twig-like bodies and wing patterns that blend with the surrounding foliage. Their colors, shapes, and even vein-like markings mirror the appearances of leaves, so when they rest on plants they break up their outline and become hard for predators, like birds, to detect. Some species also sway or hold their wings in a way that mimics a fluttering leaf, further reducing visibility. This defensive strategy helps them survive by avoiding predation, which is the strongest ecological pressure driving this trait.

While katydids do rely on songs to attract mates, mimicry itself isn’t about signaling to other insects or humans or about regulating body temperature. It’s primarily about staying hidden from those that would eat them, which is why hiding from predators is the best description of its purpose.
