Fig. 1 . The seasonal abundance of the three most common bumble bee species (Bombus sp.) across sampling dates in 2019.
Fig. 2 . Abundance and the niche overlap of species pairs for the three most common bumble bee species (Bombus sp.).Data from both years are shown. Statistics are shown for the Pearson correlation for each species pair.
Fig. 3 . The relationship of the proportion of nectar collectors out of total visits for Bombus festivus (and its niche overlap to the other two species, B. lepidus (R = 0.67, P = 0.007) andB. friseanus (R = 0.83, P = 0.001), respectively.
Fig. 4 . The relationship between the composite flower depth of plants visited by Bombus lepidus and B. friseanus and their niche overlap, respectively.
Table 1 . Paired T-test of the composition of flowering plants (identity and the total number of visits) of each of the three most common bumble bee species (Bombus spp., all castes) between species pairs in 2018 and 2019.
