When the weather begins to warm in early spring, caterpillars wriggle along the pipevines in the flowerbed in front of the classrooms. A single swallowtail butterfly of the species Byasa alcinous mansonensis, fresh out of its cocoon, quietly dries its wings while resting on the fingertip of a child, waiting for the moment when it can extend them and fly away.
天氣回暖的初春，教室前花圃馬兜鈴的攀藤上，幾隻毛毛蟲蠕動爬行，一隻剛剛羽化、還在晾乾翅膀的紅曙鳳蝶，靜靜棲息在小朋友的指尖上，等待展翅的時間到來。
