These thermal images show the presence of heat during this experiment. The color green indicates the presence of bees in the experimental hive. Red and white areas indicate temperatures above 37 degrees Celsius.
The top panel depicts the experimental hive. It shows that the high heat area, colored red, grew within three minutes of cooling and disappeared with nine minutes. The bottom panel shows how the control panel gradually dissipated heat. There, heat persisted after 18 minutes of cooling
