Perreyia flavipes Konow, 1899 (Pergidae: Perreyinae) is a sawfly species with gregarious larvae commonly found in open areas in southern Brazil through Uruguay and northern Argentina. The combination of highly gregarious larvae with the production of a variety of toxins in P. flavipes has led to severe cases of intoxication in a variety of livestock species. Over the years, considerable information was discovered on the larval natural history of P. flavipes; however, virtually nothing is known about the adult behavior, particularly because of its short life-span. In this study, we report on the first extensive study on the adult behavior of P. flavipes, including movement, mating (with oviposition and maternal care), and thanatosis. Our results show some unusual behavioral adaptations presented by P. flavipes, such as irregular activity behavior (i.e., deficient gait pattern), thanatosis behavior-like display, and primitive maternal care. Individual behavioral acts are described and compared among sexes, and their potential functions are discussed.
黄足佩雷叶蜂（Perreyia flavipes Konow，1899年）（叶蜂科：佩雷叶蜂亚科）是一种叶蜂，其幼虫群居，常见于巴西南部、乌拉圭和阿根廷北部的开阔地区。黄足佩雷叶蜂高度群居的幼虫与产生多种毒素的特性相结合，导致多种家畜出现严重中毒病例。多年来，人们发现了大量关于黄足佩雷叶蜂幼虫自然史的信息；然而，对于成虫的行为几乎一无所知，尤其是因为其寿命较短。在本研究中，我们报告了对黄足佩雷叶蜂成虫行为的首次广泛研究，包括活动、交配（包括产卵和母性照料）以及假死行为。我们的结果显示了黄足佩雷叶蜂呈现出的一些不寻常的行为适应性，例如不规则的活动行为（即步态模式缺陷）、类似假死行为的展示以及原始的母性照料。描述了个体行为动作并在两性之间进行了比较，并讨论了它们的潜在功能。
