The Psocodea Species File works to build a comprehensive source for knowledge about the world’s lice and booklice. Information found here includes valid names, synonyms, bibliographic data, specimen data, images, and distributions for lice and booklice of the world. Our site seeks to include and serve researchers in taxonomy, systematics, ecology, ethology, conservation, and evolution, as well as educators, policy makers, and citizen scientists. See our About page for an overview of the project, its data, the development and maintenance team, and details about how you can access the data, contribute, contact us, or get help.
