Differences in body size of the three bumblebee species.
The thorax widths of (a) queens, (b) males and (c) workers of B. lucorum, B. magnus and B. cryptarum. Box and whisker plots compare medians. Numbers give sample sizes. Different letters denote categories for which the means are significantly different (P < 0.01). The plots are based on raw data.
