This Bizarre Insect Turns Pink to Green in Just 11 Days A katydid changes color from pink to green to match leaf development, showing advanced camouflage adaptation in rainforests. A rare rainforest insect can transform its appearance in a matter of days, shifting from bright pink to leaf green in a way that may help it avoid predators. Researchers report that Arota festae, a tropical katydid also known as a “bush cricket,” undergoes this dramatic color change over about two weeks. The species lives in the forests of Panama, Colombia, and Suriname, where survival often depends on staying hidden in plain sight. The discovery, published in Ecology, began when scientists noticed a female katydid resting under a light at the Smithsonian Tropical Research Institute’s field station on Barro Colorado Island in Panama. At first, she stood out vividly in hot pink. Just eleven days later, she had blended in completely after turning green. Camouflage and Leaf Mimicry The researchers believe this transformation is not random. Instead, it likely mirrors a common plant strategy known as “delayed greening.” In many tropical species, newly sprouted leaves emerge in bright pink or red shades before gradually turning green as they mature. That timing may be critical. On Barro Colorado Island, about one-third of plant... https://scitechdaily.com/this-bizarre-insect-turns-pink-to-green-in-just-11-days/
