dc.description.abstract | Honeybees [1] and bumblebees [2] perform learning flights on leaving a newly discovered flower. During these flights, bees spend a portion of the time turning back to face the flower when they can memorise views of the flower and its surroundings. In honeybees, learning flights become longer, when the reward offered by a flower is increased [3]. We show here that bumblebees behave in a similar way and we add that bumblebees face an artificial flower more when the concentration of the sucrose solution that the flower provides is higher. The surprising finding is that that a bee’s size determines what a bumblebee regards as a 'low' or a 'high' concentration and so affects its learning behaviour. The larger bees in a sample of foragers only enhance their flower facing when the sucrose concentration is in the upper range of the flowers that are naturally available to bees [4]. In contrast, smaller bees invest the same effort in facing flowers, whether the concentration is high or low, but their effort is less than that of larger bees. The way in which different sized bees distribute their effort when learning about flowers parallels the foraging behaviour of a colony. Large bumblebees [5] are able to carry larger loads and explore further from the nest than smaller ones [6, 7]. Small ones with a smaller flight range and carrying capacity cannot afford to be as selective and so accept a wider range of flowers. | en_GB |

dc.description | Frasnelli_etal_2020_data_Fig1.xlxs: Coordinates, body angle and distance to nest of the example trajectory shown in Figure 1 for a bee performing its first learning flight at the flower.
Frasnelli_etal_2020_data_Fig2.xlxs: Body orientations of bees (40 degree bins) during their first learning flight. Four groups were tested with either 10%, 20%, 30% or 50% sucrose solution. In the next experiment two groups were tested with 20% and 50%. Body orientations (40 degree bins) are given as well as distances at which bees faced the flower.
Frasnelli_etal_2020_data_Fig3_4B.xlsx: Data illustrate the influence of individual body size on flower facing. Given are the number of frames, the number of bouts and the proportion of flower facing.
Frasnelli_etal_2020_data_Fig4A.xlsx: Relation between individual body size and the volume bees imbibed of the 20% or 50% sucrose solution. | en_GB |
