Table 1: List of families and genera collected in the environment around L. malachurum nesting sites, and relative use of plant genera/pollen types (richness of used taxon/richness in the environment*100) in the families where genera/type-level identification of pollen from bees was possible. Genera/types in bold were found in bee pollen loads. Only taxa represented in pollen loads by more than 1% were considered.
