摘要： Lepidopteran larvae, commonly known as caterpillars, exhibit diverse adaptive strategies for survival in various ecosystems, including the development of venom systems with urticating structures like spines and setae. Some of these structures are associated with venom glands, while others are not. The location of gland cells within urticating hairs varies among species. Based on current research and a comprehensive phylogenetic analysis of Lepidoptera, venomous lepidopterans are estimated to have evolved over 50-110 million years, encompassing approximately 16 families and 55 thousand species, within which venomous species are found. Lepidopteran venom represents a valuable genetic resource for advancing our understanding of ecology, evolution, and biochemistry. Although research on lepidopteran venom is limited, important progress has been made in some groups, such as the Saturniidae family, elucidating its composition, function, and evolution. This review consolidates current knowledge on lepidopteran venom systems, providing insights into the evolutionary development of stings and venom constituents, and the discovery of bioactive molecules with potential medical and agricultural significance. Taking advantage of multi-omics approaches, gene interference, and editing methodologies, there is a growing impetus for deciphering the composition and function of lepidopteran venom across a broader taxonomic range, and to uncover the genetic mechanisms underlying its evolution.
