Invasive yellow-legged hornet spotted in Pacific Northwest

A live yellow-legged hornet (Vespa velutina) was found April 30 aboard a ship at the Port of Vancouver on the Lower Columbia River and is being monitored after traps were set; experts warn this invasive, more mobile hornet—smaller than the notorious northern giant hornet—could threaten Northwest honeybees and agriculture and might spread coast-to-coast, though no further nests have been found yet.
