Abstract

Abstract: 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.
