Predatory mantis species, such as Kongobatha diademata, have a remarkable behavior called leaf-planking. This involves flattening their bodies against leaves, which enables them to blend in effortlessly with their surroundings. Researchers have recently discovered a sensory organ known as the “gustifolium” on the chest of some mantises. Unlike anything seen in mantises or other predatory insects, this bristly bump may have evolved to assist these insects in their specialized lifestyles.
Some praying mantis species, particularly those found in Asia and Australia, engage in leaf-planking as a unique adaptation that helps them remain camouflaged and avoid detection by predators or prey. The practice of leaf-planking and the discovery of the gustifolium provide insight into the fascinating adaptations and behaviors of these predatory insects.
