(abstract) This dataset was produced in the framework of the work package 1 (task 1) of the Horizon EU project Safeguard. We aimed to mobilise EU experts and data to compile and make available distributional data for bees, butterflies, moths and hoverflies. This will allow us to assess the magnitude, scale and extent of status and trends in pollinator distributions, diversity, abundance, communities and plant-pollinator networks. (method) Regarding distribution data for bees, UMons have been in contact with 23 bee taxonomists, 52 national champions and 5 museums. To date, we collected 52 bio-geographical databases of European bees from both restricted (i.e. databases shared under ad hoc agreement) and public (i.e. openly accessible databases) sources. Regarding distributional data for hoverflies, the starting point was the recently published in the IUCN Red List of hoverflies. To expand the number of species with precise distributional data on syrphid flies, UNSPMF further contacted taxonomists working with this species group : Gunilla Stahls from Finland; Jeroen van Steenis, Wouter van Steenis and Gerard Pennards from Netherlands; Grigory Popov from Ukraine; Santos Rojo from Spain; Axel Ssymank from Germany; Libor Mazanek from Czech Republic; Daniele Sommaggio from Italy. They provided additional data and conducted validation of the existing data, but also engaged additional experts who provided the data. For the butterflies and the moth, the data was collected by UFZ and come from an original initiative of the scientific expert on those two groups. As the publication of the row data of some databases (e.g. bees from The Netherlands) required the clustering of the spatial records to geographic grid squares (e.g. 10x10 km²), we simplified all the records in the present dataset. (dataset) We consider as a data, a record that includes the following information: the name of the species, the coordinates where the species was collected. Additional information were collected (e.g. collector, determinator, number of the individuals collected, sex, data owner and reference code) but were not displayed in the present dataset. The aggregation of bee databases include 4,837,731 row data for bees, 680,641 row data for hoverflies, 1,209,320 row data for butterflies and 6,862,835 row data for moths.
