An estimated 25,000 bumblebees have been found dead in a Target parking lot in Wilsonville since Saturday, the largest known incident of bumblebee deaths in the United States, according to the Xerces Society. Preliminary information suggests pesticides may be at fault.
The Oregon Department of Agriculture received reports of bees and other insects falling out of 55 blooming European linden trees Monday from the Xerces Society for Invertebrate Conservation.
The bees were still dying on Wednesday. Yellow-faced bees fell from the trees, twitching on their backs or wandering in tight circles on the asphalt. Some honeybees and ladybugs were also found dead. A few dead bumblebees even clung to linden flowers, while hundreds littered the lot.
