The Odonata of China: a data-driven, open-access resource for biodiversity research and conservation

Database (Oxford). 2025 Jan 18;2025:baaf077. doi: 10.1093/database/baaf077.

ABSTRACT

Odonata (dragonflies and damselflies) are among the most ancient winged insects, with over 900 species recorded in China, representing the highest global diversity. However, the lack of a centralized database integrating morphological, ecological, and multiomics data has hindered large-scale research and conservation efforts. We present Odonata of China (http://dragonflies.kiz.ac.cn), a comprehensive database compiling taxonomic, biogeographic, phenotypic, and multiomics data for 820 species across 3 suborders, 22 families, and 172 genera. The database features advanced search modules (direct, phylogenetic, and map-based), genomic and transcriptomic data for 20 representative families, and high-resolution images. The platform is constructed based on mainstream open-source technologies, ensuring scalability and reproducibility. Odonata of China provides a critical resource for evolutionary biology, conservation, and ecological studies. By integrating heterogeneous data types and leveraging modern technologies, this database bridges a significant gap in invertebrate biodiversity informatics and supports global initiatives to monitor insect declines.
