Jun 09, 2009 . What are Ocelli? Ocelli (singular ocellus) is Latin and means little eye. One to three Ocelli can be found in many insects, located at different positions on their heads. Ocelli have evolved as a second visual system, in addition to the compound eyes that insects are famous for.

An ocellus (plural: Ocelli) is a type of photoreceptor organ in animals.Also called "simple eyes", Ocelli are miniature eyes capable of sensing light but not distinguishing its direction. See also stemmata, which are structurally similar. Ocelli are found in many invertebrates. Insects in particular have two types of Ocelli, dorsal Ocelli and lateral Ocelli.

The Ocelli of some flying insects, locusts and dragonflies, have been shown to function as horizon detectors involved in the visual stabilization of course. In a walking insect, the desert ant Cataglyphis, it is now shown that the Ocelli can read compass information from the blue sky. When the ant's compound eyes are occluded and both sun and ...

Normally, flying insects have one to three simple Ocelli or eyes in the head apart from a pair of evolved compound eyes. However, these ‘eyelike markings’ can also be found on the wings of some insects like the butterflies. There is usually a spot of color within a colored ring. Insects possess segmented but interconnected bodies.

Dragonfly Ocelli appear to be especially highly developed and specialised visual organs, which may underlie their exceptional acrobatic abilities. Lateral Ocelli have a mixture of rod cells and cone cells and are found on the sides of the head, one to six on each side.
Lateral Ocelli have a mixture of rod cells and cone cells and are found on the sides of the head, one to six on each side. Lateral Ocelli are the only eyes of the larvae of several orders of insects ( fleas, springtails, silverfish, and Strepsiptera).
Dorsal Ocelli are light-sensitive organs found on the dorsal (top-most) surface or frontal surface of the head. They tend to be larger and more strongly expressed in flying insects (particularly bees, wasps, dragonflies and locusts), where they are typically found as a triplet.
You are: Home > Insects > Glossary > Definition of 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.
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.
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.
Ocelli are simple light–dark sensitive eyes with low spatial resolution, occurring throughout pan-arthropods, which are located on top of the head and which may contribute to control of locomotion.
