  2. Arthropod eye - Wikipedia

    en.wikipedia.org/wiki/Arthropod_eye

    Most arthropods have at least one of two types of eye: lateral compound eyes, and smaller median ocelli, which are simple eyes. [2] When both are present, the two eye types are used in concert because each has its own advantage. [3] Some insect larvae, e.g., caterpillars, have a different type of simple eye known as stemmata.

    en.wikipedia.org/wiki/Simple_eye_in_invertebrates

    The term "ocellus" (plural ocelli) is derived from the Latin oculus (eye), and literally means "little eye". In insects, two distinct ocellus types exist: [9] dorsal (top-most) ocelli, and lateral ocelli (often referred to as ocelli and stemmata, respectively), most insects have dorsal ocelli while stemmata are found in the larvae of some ...

    An image of a house fly compound eye surface by using scanning electron microscope Anatomy of the compound eye of an insect Arthropods such as this blue bottle fly have compound eyes. A compound eye may consist of thousands of individual photoreceptor units or ommatidia (ommatidium, singular). The image perceived is a combination of inputs from ...

    Compound eye of a house centipede Compound eye of a dragonfly. A compound eye is a visual organ found in arthropods such as insects and crustaceans.It may consist of thousands of ommatidia, [1] which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.

    Although composed of over 16,000 cells, [6] the Drosophila compound eye is a simple repetitive pattern of 700 to 750 ommatidia, [7] initiated in the larval eye imaginal disc. Each ommatidium consists of 14 neighboring cells: 8 photoreceptor neurons in the core, 4 non-neuronal cone cells and 2 primary pigment cells. [ 6 ]

    The optic(al) lobe of arthropods is a structure of the protocerebrum that sits behind the arthropod eye (mostly compound eyes) and is responsible for the processing of the visual information. It is made up of three layers: Lamina (ganglionaris)
