Ambient Air Temperature Does Not Predict whether Small or Large Workers Forage in Bumble Bees (Bombus impatiens)

Figure 5

Foragers of different body sizes had similar maximum and minimum foraging temperatures within the temperature range studied here (up to 36°C ambient temperature). The relationship of thorax width and maximum foraging temperature was only significant if the outlier (marked with an arrow) of one bee which only made a single trip in the whole study was included. Shown are (a) ambient temperature and (b) temperature measured in nest; each data point is the maximum or minimum of all observations for that bee. In total 81 bees are shown.
