小知識 Fun Face

不同的直翅目昆蟲有不同的特定適應性。蝗蟲在白天活躍,顏色與草和花的顏色相似(綠色、黃色、粉紅色)。蟋蟀通常是夜行性的,身體顏色較深。知了通常棲息在葉子上,經常呈綠色,翅膀看起來像有葉脈或棕色斑點的葉子。

Different orthopterans have different specific adaptations. Grasshoppers are active during the day, their color is similar to the color of grass and flowers (green, yellow, pink). Crickets are usually nocturnal and their bodies are darker in color. Katydids are usually found on leaves and are often green and have wings that look like leaves with veins or brown spots.
