Bee Quiz: Immaculate Navigation
2.) How do bees navigate the air?
Ever wonder how tiny bees fly between walls and onto surfaces effortlessly? Not all winged creatures possess such Olympian grace. We've seen pigeons completely botch the landing, but honeybees always seem to get it right.
According to a 2002 Australian National University study, honeybees have complex neural mechanisms at work in flight: they take cues from optic flow. Bees balance speed of the images of the two walls to remain at the midpoint between them. They hold the average image velocity constant to maintain their speed and to slow down as they approach a surface to make a safe landing.
