Farmers in the U.S. West face a creepy scourge every eight years or so: Swarms of ravenous insects that can decimate crops and cause slippery, bug-slick car crashes as they march across highways and roads. The 2017 swarms are affecting Idaho, Oregon, and other Western states. (AP Photo/Debra Reid, File)
