Long before facial recognition systems were invented by humans, wasps have been using their own facial recognition “systems.” By using a combination of facial recognition and odor cues, wasps are able to identify wasps from their own colonies vs. enemy wasps out for their resources. Queen Mary, University of London scientists discovered that the Southeast Asia wasp species Liostenogaster flavolineata uses facial recognition in an experiment utilizing friend and enemy wasp odor drenched filter paper. With the scented filter paper, the wasps tended to let enemies into their colony. With facial recognition, wasps attacked colony-mates by mistake. Scientists believe while wasps use both odor and facial recognition, their determining factor in identifying wasp friends or enemies is facial recognition.
