Pollinator distributions of North America for climate ranging from 20,000 years ago to year 2100

This data publication contains 2280 raster digital files of modeled potential distributions for 228 pollinator species that were observed from 1990-2022 during the summer months of June, July, and August in North America under the following 10 climates: 1981-2010; 20,000 years ago (ka); 10 ka; 6 ka; and six end-of-century (2071-2100) climate projections under two emission scenarios. Pollinator species include 88 butterflies, 69 moths, 12 flies, 17 wasps, 18 bees, and 24 beetles. Mean accuracies of withheld samples for models, based on climate of 1981-2010, ranged in values from 0.93 to 0.95, depending on the species. Mean annual temperature was found to be the most important variable for the greatest number of species, for summer distributions.
The purpose of this project was to provide pollinator distributions under different climates in North America.
