蚜蟲和螞蟻有著共生的關係，蚜蟲分泌蜜露給螞蟻，而當有天敵侵擾時，螞蟻則負起保護蚜蟲的責任。圖中一隻食蚜蠅幼蟲正在捕食蚜蟲，螞蟻勢單力薄，只能束手無策地待在一旁。但食蚜蠅幼蟲絲毫沒有發現自己也身陷危機之中，最後難逃螳螂的魔掌。展現出自然界弱肉強食與奇妙的共生關係。

Aphids and ants have a symbiotic relationship. Aphids secrete honeydew to feed ants while ants protect aphids. In these images, a dramatic scenario is unfolding: a syrphid larva is preying on an aphid. An ant, instead of performing its duty, stands and observes. A praying mantis is nearby and eventually snatches the syrphid larva. These images demonstrate the law of survival of the fittest in the natural world, as well as intriguing symbiotic relationships.
