Ocelli - Entomologists' glossary - Amateur Entomologists

Ocelli (singular Ocellus) are simple photo-receptors (light detecting organs). They consist of a single lens and several sensory cells. Unlike compound eyes, Ocelli do not form a complex image of the environment but are used to detect movement. Most arthropods possess Ocelli. Some species of arthropod do not possess compound eyes and only have Ocelli.

I've noticed that it's a pretty common trope in alien spec

Insects don't always have just 2 eyes. Honey bees and related species for example have the two compound eyes but they also have three Ocelli which are used to detect the sun and orient to it properly. They are visual sensors just not as complex as the compound eyes. This is why I specified complex eyes. Vertebrates also used to have a 3rd simple eye exactly in the same …
