bodysize                Converts the intertegular distance (IT) and
                        co-variates to body size in dry weight (mg) for
                        bees or hoverflies.
foragedist              Converts body weight to measures of foraging
                        distance for bees.
headwidthsize           Converts pollinator (Diptera, Hymenoptera and
                        Lepidoptera) head width (mm) to body size (dry
                        weight (mg)).
lengthsize              Converts body length to body size (body weight
                        (mg)) for three pollinating insect groups
                        (Diptera, Hymenoptera and Lepidoptera).
lengthwidthsize         Converts pollinator body length*body width to
                        body size (dry weight (mg)).
nectarload              Converts bee body length (mm) to total field
                        nectar load (ul).
pollimetry_dataset      Body size and intertegular distance
                        measurements of ~4500 pollinating insect
                        specimens.
tonguelength            Converts ITD (cm) to tongue length for bees.
wingloading             Converts intertegular distance (mm) to wing
                        loading (mg mm2).
