Whilst we know a lot about the foraging preferences of honey bees, little is known about the foraging preferences of bumblebees. In this new study, we show that whilst the majority of foraging bumblebees are generalists (feeding on both pollen and nectar), some bumblebees do specialise on only foraging for pollen, and some specialise on nectar. Believing this may be linked to the different sizes of bumblebee foragers that a colony produces, we set about looking for relationships between this foraging preference and the body size, fat content, sucrose sensitivity and ovary size of the workers.
