Abstract
This dataset contains continuous predicted habitat suitability maps for multiple bee and hoverfly functional groups across urban land-cover categories. Habitat suitability predictions were generated using urban land-cover variables to assess associations between pollinator functional groups and different urban habitat types. The dataset includes suitability surfaces for each functional group and associated urban land-cover classifications, enabling comparison of predicted suitability across habitat categories such as dense urban fabric, green urban areas, industrial land, and other urban land-cover types. Functional groups represented include multiple bee and hoverfly groups, including leafcutter bees and hoverflies with phytophagous larvae. The dataset is intended to support analyses of pollinator responses to urban environments, urban biodiversity assessment, and conservation planning.

Description of the data and file structure
Contemporary field data was collected by conducting pollinator surveys at two sites in Liverpool. Long-term historical data was provided by Merseyside BioBank and the Lancashire Wildlife Trust spanning the Merseyside area.
