Abstract: Motivation: Aquatic insects comprise 64% of the freshwater animal diversityand are widely 6 used as bioindicators to assess water quality impairment andfreshwater ecosystem health, as well as to test ecological hypotheses. Despitetheir importance, a comprehensive, global database of aquatic insectoccurrences for mapping freshwater biodiversity in macroecological studies andapplied freshwater research is missing. We aim to fill this gap and present theGlobal EPTO Database that includes worldwide geo-referenced aquatic insect occurrence recordsfor four major taxa groups: Ephemeroptera, Plecoptera, Trichoptera and Odonata (EPTO).Main type of variablescontained: A total of 8,368,467 occurrencerecords globally, of which 8,319,689 (99%) are publicly available. The recordsare attributed to the corresponding drainage basin and sub-catchment based onthe Hydrography90m dataset and are accompanied by the elevation value, thefreshwater ecoregion and the protection status of their location. Spatial location and grain: The database covers the global extent, with 86% of the observation records havingcoordinates with at least four decimal digits (11.1 m precision at the equator) in the WGS84 coordinate reference system. Time period and grain: Sampling years span from 1951 to 2021. 99% of the records have informationon the year of the observation, 95% on the year and month, while 94% have a complete date. In the case of 8sub-datasets, exact dates can be retrieved upon communication with the datacontributors. Major taxa and level of measurement: Ephemeroptera, Plecoptera, Trichoptera and Odonata, standardised at the genustaxonomic level. We provide species names for 7,727,980 (93%) records without furthertaxonomic verification. Software format: The entiretab-separated value (.csv) database can be downloaded at https://fred.igb-berlin.de/data/package/725and visualised at https://geo.igb- berlin.de/maps/621/view. Fifty individual datasets are also available in https://fred.igb  berlin.de, while 6 datasets have restricted access. For the latter, weshare metadata and the contact details of the authors.
