Table 3.

Total amount (mg/mg body mass) of nectar and pollen consumed per day for different life stages and castes of bumble bees (Bombus spp.) and honey bees (Apis mellifera L.).

		Amount Consumed Per Day (mg/mg body mass)*
Taxon	Caste	Sucrose/Nectar	Pollen
honey bee	worker	0.32–5.0	0–0.12
bumble bee	worker	0.40–2.2	0.11–0.16
bumble bee	queen	0.30–2.4	0.067–0.11

^*Values were calculated using consumption values from Table 2 and the median body mass for bumble bees (queens: 550 mg, workers: 184 mg) and mean body mass for honey bees (workers: 100 mg).
