Some predatory animals, represented by large carnivores, forage in groups and benefit from this behavior. We tested the hypothesis that carnivorous plants also benefit from group foraging to improve the efficiency of trapping large prey using Drosera makinoi (Droseraceae). As a result of our field observations, it was found that larger neighboring D. makinoi density yields a greater number of large preys (≥3 mm) and total prey biomass per plant. Results showed that a total of 43.4% of the events to trap large prey was achieved by two trap leaves belonging to two neighboring D. makinoi plants. Our results proved that group foraging in D. makinoi enables them to trap large prey.

食肉植物的群体觅食：食肉植物Drosera makinoi（Droseraceae）在大型群体中捕获更大的猎物更有效。

一些以大型食肉动物为代表的掠食性动物成群觅食，并从中受益。我们测试了这样的假说，即食肉植物也可以从群体觅食中受益，以提高捕捞果蝇（Drosera makinoi）（Droseraceae）捕食大型猎物的效率。根据我们的实地观察结果，发现较大的邻近D. makinoi密度会产生大量的大型猎物（≥3 mm）和每棵植物捕食的总生物量。结果表明，总共43.4％的捕获大型猎物的事件是由属于两个相邻的D. makinoi植物的两个捕获叶实现的。我们的结果证明，在D. makinoi中进行群体觅食可以使他们捕获大型猎物。
