Whats Happening To the Flies?

May 15, 2017: In this video, you will see a farm in SE Michigan that is clearly missing a life form that is nowhere to be found, there should have been thousands but there were none. He tends to his farm everyday, has for many years...this year something changed...and he noticed right away. (Any Entomologists here?)
