Table 2.

Differences in the plant species assemblages used as forage resources by the three lucorum complex species. Bray–Curtis distance measures showing the dissimilarity between the diets of each caste of each of the three bumblebee species. A value of 0 indicates that the two assemblages were identical, whereas a value of 1 indicates that they were completely different. B. magnus males are not included because the sample size was too low: Only overwintered queens are included
