Data: Pairwise associations between species of <i>Andrena </i>and species of plants in the Cazorla mountain range (SE Spain)

Specimens of<i> Andrena</i> bees (Hymenoptera, Andrenidae) were collected in the Cazorla mountain range (Jaén province, southeastern Spain) during pollinator censuses conducted over 1997-2024, in the course of bee surveys during 1982-2025, or in connection with ecological research on bee thermal ecology (Herrera 1995, Herrera et al. 2023, Herrera 2024). Collected bees (1,948 specimens from 89 different <i>Andrena</i> species) had associated data on the species of plant in whose flowers they were probing for nectar and/or gathering pollen when captured. These data have been combined to elucidate the composition of food plants used by the species of <i>Andrena</i> occurring in the region. Collectively, species of <i>Andrena</i> were recorded visiting flowers of 129 different plant species from 81 genera in 33 families.This data repository consist of the following single file:<b>andrena.specs</b>Delimited text file containing plant-<i>Andrena</i> species pairs, plant family, and the number of individuals recorded for each bee-plant combination. Variable names are in the first row of the file. Bee nomenclature follows Wood (2023), and plant nomenclature follows Gómez Mercado (2011) with only minor updates.References citedGómez Mercado F (2011) Vegetación y flora de la Sierra de Cazorla.
