These data list individual non-native insect species established in nine regions around the globe (New Zealand, South Korea, Japan, Okinawa, Ogasawara, Europe, Great Britain, North America (north of Mexico), Hawaii, Galapagos, Chile and South Africa). Taxonomy, attributes and occurrences for each taxa are included, as well as a source table which can be used to find more details on occurrences. This dataset was assembled from various sources by an interdisciplinary scientific working group funded by the National Socio-Environmental Synthesis Center. See the main source references in the References metadata section for this publication. Data have been cleaned of most typographic and taxonomic errors using the code in the R package insectcleanr: Initial release (DOI: 10.5281/zenodo.4555787), which is based on the Global Biodiversity Information Facility (GBIF) taxonomic backbone (GBIF Secretariat (2021).
