Using deep learning to find Murder Hornets (and protect bees!)

As if a pandemic isn't troubling enough, my news feed is now full of images of Murder Hornets. These oversized wasps have a menacing scowl and a venomous stinger, with enough venom to be lethal to humans. But that's not what has most folks nervous: Murder hornets, also known as Asian giant hornets (Vespa mandarinia), have been attacking honeybees in...
