Bees flying near cars are dying by the millions, a roadkill study suggests

Scientists put sticky traps on car bumpers to tally how many bees get hit on a typical trip

Scientists studying bee roadkill were able to identify bees belonging to more than a dozen different genera caught in sticky paper traps put on car bumpers, as seen in this composite image.
