2000年7 ~ 9月，通过对稻田狼蛛Pardosapseudoannulata和Piratasubpiraticus的直接观察，阐明了它们的食性。7月份，拟环纹蚤捕食量最大的是双翅目昆虫，其次是拟盗龙蚤，分别占捕食量的50%和20%以上。8月份，双翅目昆虫的比例急剧下降，捕食量最大的是跳甲，分别占拟环纹蚤和拟水狼蛛捕食昆虫和蜘蛛总量的60%和70%以上。在九月，捕食者，如狼蛛和水生异翅目，经常在他们的饮食观察。总的来说，拟环纹叶蝉和拟水扁叶蝉捕食数量最多的是绿色稻叶蝉，其次是摇蚊。
The diets of the wolf spiders Pardosa pseudoannulata and Pirata subpiraticus were elucidated by direct observation in paddies from July to September 2000. In July, dipterous insects were the most numerous prey consumed by P. pseudoannulata and the second numerous prey consumed by P. subpiraticus, comprising over 50% and over 20% of their respective diets. In contrast, in August, the proportion of dipterous insects decreased dramatically and hoppers were the most numerous prey, comprising over 60% and over 70% of all insects and spiders consumed by P. pseudoannulata and P. subpiraticus, respectively. In September, predators such as wolf spiders and aquatic Heteroptera were frequently observed in their diets. Overall, the green rice leafhopper, Nephotenix cincticeps, was the most numerous prey consumed by P. pseudoannulata and P. subpiraticus, followed by chironomids.
