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

Figure 2

Bees of a wide range of body sizes were found to forage at all ambient air temperatures. Data are pooled here for both colonies; shown are medians (lines), quartiles (boxes), and ranges (whiskers) ($n=70$ bees for 16°, $n=65$ for 21°, $n=67$ for 26°, $n=71$ for 31°, $n=73$ for 36°).
