These data were collected to estimate occupancy of Bombus affinis at two spatial scales: 10x10km grid cells and 3.14 hectare sampling units with unknown occupancy in Wisconsin, Minnesota, and Illinois 2022-2024. Data were also used to determine relationships between the area of developed land and Bombus affinis occupancy at both spatial scales and to determine factors affecting Bombus affinis detection probability.
