Figure 2. Temperature and inter-visit-interval.

A scatter-plot of every individual bee’s longest inter-visit-interval and the temperature inside the operant chamber of the apparatus during an individual bee’s longest inter-visit-interval is presented. Two subjects did not have any temperature data. No bees above 40 degrees finished the experiment. However, long inter-visit-intervals can still be observed for bees with comparatively lower temperatures; indeed the subject with the lowest temperature had a higher inter-visit-interval than more than half of the bees.
