Insect compound eyesMDPI

The use of the MW for navigation is the result of evolutionary processes applied to particular insects in particular habitats.
Insect compound eyes are highly adaptable sensory structures.
Insects commonly possess one of two main types of compound eyes, apposition eyes and superposition eyes (Figure 2 ), each composed of cylindrical optical units known as ommatidia.
On moonlit nights , large yellow underwing moths navigate using the moon’s azimuth.
Nocturnal insects can resolve only a few of the brightest individual stars, but integrated over its area, the MW is a bright and continuous object that is unambiguous in the night sky.
The investigation of insect navigation not only unveils the fascinating adaptations of these tiny navigators but also provides valuable insights for biomimicry.
Despite insects having tiny brains and small compound eyes, the nocturnal dung beetle Scarabaeus satyrus can move in straight lines while it rolls its dung balls on a moonless night.
Somehow, the use of the MW is possible despite this effect, or maybe the compass behavior has evolved because of this effect.
