Fig. 4 in Favourite plants of wild bees

Fig. 4. Favourite plants as pollen hosts. Scaled pollen scores for each of the identified 34 "high visitor richness" plant species (according to Fig. 3). The scaled pollen score for one plant species is the percentage of other plant species that are visited by a lower number of bee species, e.g. a scaled pollen score of 100 shows that all other plant species in the database were visited by a lower number of bee species. The maximum number of bee species visiting one plant species is 71 and the total number of plant species described in Westrich (2018) is 494. The average scaled pollen score of 50 is indicated by the dashed red line.
