一條蝴蝶毛蟲在檸檬樹上誕生了！牠本來應該一直在那棵樹上生長，直到蛻變成蛹，再變成蝴蝶。但是一場暴風雨破壞了原定計畫，令毛蟲從樹上掉了下來，被風雨帶走。

毛蟲必須在約三天之內，回到牠的樹上才能蛻變成蝴蝶。牠要展開一場與時間競賽的旅程，穿越幾個微型生態系統：花壇、草坪、沙路以至森林。途上牠遇到不同的小生物，例如螢火蟲、黑褐毛山蟻或螳螂，有時還會出現驚險場面。

透過這條毛蟲的求生之旅，我們探索多個微型世界，在那兒人類的一小步，就是一隻小昆蟲一生的長征，豐富多彩，令人讚嘆！

Becoming Butterfly

On a lemon tree, a butterfly caterpillar is born. It is supposed to grow there until morphing into a chrysalis and then a butterfly. But a storm destroys this preset scheme and makes the caterpillar fall and get carried away by the rain and the wind.

The caterpillar has only about 3 days to get back to its tree, the only place where it can achieve its mutation into a butterfly. It undertakes a journey against the clock, passing through several miniaturized ecosystems: the flowerbed, the lawn, the sand alley or the forest. On its way, it makes encounters, dangerous or not, such as the glow worm, the lasius niger ant or the praying mantis.

Through this caterpillar’s journey of survival, we discover the incredible richness of microworlds where one small step for man is a lifetime expedition for a tiny insect.
