瓢蟲、螞蟻與蚜蟲的四角習題 ｜The Four-Way Puzzle of Ladybugs, Ants, Aphids, and Plants

Asian lady beetles constantly raid colonies of aphids, only to be chased away again and again by acrobat ants. Aphids feed on plant sap and produce a sugary substance called honeydew — a favorite food source for ants. To protect these tiny “drink factories,” the ants fiercely defend the aphids from hungry lady beetles. As a result, plants, aphids, lady beetles, and ants become entangled in a fascinating four-way relationship of conflict and symbiosis. 大自然小故事 05 / 愛吃蚜蟲的赤星瓢蟲，總是不斷突襲蚜蟲群，卻也一次次遭到舉尾蟻驅趕追咬。 原來，吸食植物汁液的蚜蟲，會排出含糖的蜜露，而這正是螞蟻們喜愛的食物來源。 為了守住這群會產生「甜飲料」的蚜蟲，螞蟻便成了牠們最兇悍的保鑣。 於是，植物、蚜蟲、瓢蟲與螞蟻之間，也形成了一道既衝突又共生的自然四角關係。 #瓢蟲 #蚜蟲 #舉尾蟻 #螞蟻 #食物鏈 #nature #insects #ladybugs #aphids #ants
