食性 Diet

成蟲是泛食性雜食動物，伺機取食軟體昆蟲、花粉和蜜露。而幼蟲 (幾個科的幼蟲) 食性為高度專門化的，例如，草蜻蛉幼蟲以蚜蟲和其他軟體節肢動物 (如早期的毛蟲和蟎) 為食。

Adults are generalist omnivores, feeding opportunistically on soft-bodied insects, pollen, and honeydew. While larvae (in several families) have highly specialized in its diet, for example, common lacewings larvae feed on aphids and other soft-bodied arthropods like early caterpillars and mites.

小知識 Fun Fact

此目下的科有不同的方法對付掠食者，有些家族的背上有固定碎屑的剛毛，利用這個「垃圾袋」作為偽裝和抵禦掠食者的盾牌。串珠草蜻蛉在偵測到潛在掠食者時，會模仿樹枝輕輕擺動，有些草蜻蛉則會散發出令人反感的氣味來嚇跑掠食者。

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.
