In a novel test of insect intel, researchers observed that bumblebees, which had spied on a worker bee from another colony feasting on unusual flowers, later tended to visit flowers of the same color.
This talent amounts to social learning, which is picking up a new behavior from observations of another animal, say the test’s designers, Bradley D. Worden and Daniel R. Papaj of the University of Arizona in Tucson.
