Has anyone here ever done a test to see how hot it can get inside a beehive during some of the hotter days in summer? I know that the bees try to regulate the brood nest temperature to keep it in the lower 90's or so, but just seems to me that when it is 100 degrees outside and you basically have a closed up box (the hive) in the sun, it would get way above that temperature no matter how much fanning they do. If so, the brood must be able to withstand higher temperatures without harm, as I have never seen bees hauling out dead larvae or pupae in large amounts during the heat of summer, like they will when they have chilled brood.
