Bumblebees Outwit Robotic Spiders

Scientists have found that bumblebees learn from their near-death encounters with crab spiders and adapt their future foraging strategies. They watched real bees in an artificial meadow — containing yellow flowers and robotic crab spiders. Bees that had been captured spent longer inspecting flowers during subsequent foraging trips. They may outwit the spiders — but at the expense of valuable foraging time
