Pergidae
pergid sawflies
Pergidae is the third-largest family of sawflies (Hymenoptera: Symphyta), with approximately 450 described species. The family is distributed primarily in the Australasian and Neotropical regions, with South America and Australia representing the greatest diversity. Members exhibit considerable morphological variation in antennae structure, ranging from simple to pectinate or bipectinate forms, and frequently display sexual dimorphism. Several species are economically significant as agricultural pests or livestock toxins, while others have been evaluated as biological control agents.
