The Biosystematics Database of World Diptera (BDWD) provides a comprehensive portal to knowledge about dipterans as well as a framework to organize and integrate future data and knowledge. More than 150,000 species of Diptera have been described under >250,000 names. We have only begun to properly document these names, and we will undoubtedly discover many more. The BDWD provides a synonymic checklist to enable the user to find the correct name for each dipteran. A species database and web-portal are also available along with full documentation at the Diptera website.
