Intraspecific Metabolic Rate Data for Individual Colonies:
To the best of our knowledge, we have included in our analyses all available data on the intraspecific scaling of whole colony metabolic rate with colony mass.
Table S1B. Metabolic rate for colonies of the honeybee Apis mellifera. The metabolic rate corrected at 25 ºC scales with the colony mass as (95% CI: 0.51, 0.73; r2 = 0.80)
