Heat didn't kill these colonies 'beekeeper error did'.  The cause of 
death; failure in the responsibilities as a 'caretaker living creatures' 
to insure a nearby water source.   

In a honeybee thermoregulation experiment, Lindauer placed a beehive on a 
lava field in Salerno, Italy, under full sun.  Even though the exterior 
temperature was recorded to be more than 158F, Lindauer observed that the 
bees were still able to maintain the internal hive temperature between 93 
to 95F as long as they could collect water nearby.
