2.2.2 Ocelli. Ocelli are found in all cnidarian subgroups except Anthozoa. They are almost exclusively found in the motile medusa stage but very simple Ocelli, which are structurally similar to the general ocellus type of hydromedusae, have been described from the polyps of the staurozoan Stylocoronella riedli (Blumer et al., 1995). The detailed structure of cnidarian Ocelli …

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.

Insect Ocelli are relatively simple eyes that have been assigned various functions not related to pictorial vision. In some species they function as sensors of ambient light intensity, from which information is relayed to various parts of the nervous system, e.g., …

The Ocelli are single-lens eyes of the camera type, whose role is still unknown in many insects, including the studied species. The present study searched for a potential role of these visual organs in these species, by determining the physiological and optical characteristics of the Ocelli.

The term "ocellus" (plural Ocelli) is derived from the Latin oculus (eye), and literally means "little eye". Two distinct ocellus types exist: dorsal Ocelli (or simply "Ocelli"), found in most insects, and lateral Ocelli (or stemmata ), which are found in the larvae of some insect orders. They are structurally and functionally very different.

Head of Polistes with two compound eyes and three Ocelli, circled A simple eye (sometimes called a pigment pit) refers to a form of eye or an optical arrangement composed of a single lens and without an elaborate retina such as occurs in most vertebrates.
