This database contains a large dataset of Chilean flower visitors (insects) with 12,001 records from 118 species of 21 families belonging to four orders (Hymenoptera, Diptera, Lepidoptera, and Coleoptera), comprising over a century of data. This dataset contains samples from six major institutions in Chile (National Museum of Natural History, University of Chile, Metropolitan University of Education Sciences, Austral University of Chile, the Chilean Agricultural and Livestock Bureau, and Luis Peña's private entomological collection). A first effort to digitize this information was made in 2008 through the IABIN project that gathered pollinator datasets from Latin America (led by Cecilia Smith-Ramirez and conducted by Karen Yañez, supported by the Institute of Ecology and Biodiversity - IEB), but when the funding was over, the database became offline. Now, in the frame of the SURPASS2 project, we recovered this dataset, and performed a major data cleaning, updated the taxonomy, checked the geographic coordinates (where available), and standardized it to DarwinCore to make it freely available through GBIF. This endeavor adds to a previous dataset published in 2020, aiming to make this natural legacy open to everyone and encourage more research in this field.
