Families under this order have different ways against predators. Some families have setae holding items of debris on their backs and use this “trash packet” as camouflage and as a shield against predators. Beaded lacewings mimic a twig by swaying gently when a potential predator is detected. While certain lacewing emits an offensive odor to scare off predators.
