Oregon may not be the best place to be a bee. Last year, 50 000 bumblebees (Bombus sp.) died there in a parking lot. Trees had been sprayed with pesticide. It turned out that the spray was dinotefuran, one of the neonicotinoids. Three neonics are currently under a temporary ban here in Europe, but not dinotefuran which (I think) is permanently banned here.
Another 1000 bees, this time honeybees (Apis mellifera) were found dead along an Oregon road last month. Of course people’s minds turned to neonics. But it seems that this particular bee kill wasn’t about pesticides at all. It’s looking as though these bees swarmed peacefully, as honeybees do, and they got killed by cars.
