Hello, I received the answer to my question. I wanted to post it here to complete the thread. Thanks to Jerry and Aaron for the off list response, and for being so generous with your time to assist. I have the answer posted below. The information has been added to my Obscure Bee Trivia file, which is complete with source references, and also free to all who what to use it. Remember, dont show too many people this obscure bee trivia, or it wont be 'obscure' anymore. ;) Obscure Bee Fact #14 * Research has shown that some honeybee colonies may make over a half a million flights per day. An average size honeybee colony makes about 250,000 flights per day, -almost three times as many flights than all the aircraft flights in the United States on any given day.
