Detailed explanation-1: -A compound eye is a visual organ found in arthropods such as insects and crustaceans. It may consist of thousands of ommatidia, which are tiny independent photoreception units that consist of a cornea, lens, and photoreceptor cells which distinguish brightness and color.

Detailed explanation-2: -Such compound eyes are termed as apposition eyes and are found in diurnal insects like bees, grasshoppers, and butterflies. Nocturnal insects like moths, fireflies, cockroaches, and beetles have superposition compound eyes.

Detailed explanation-3: -All insects that have eyes have compound eyes. Many insects cheat and have both simple light sensing receptors and compound eyes. There are about 150, 000 described species of described true flies (Diptera) with an estimated total number of fly species to be around 240, 000.

Detailed explanation-4: -Anatomical distribution of compound eyes Most species of Arthropoda with compound eyes bear just two eyes that are located separately and symmetrically, one on each side of the head. This arrangement is called dichoptic. Examples include most insects, and most of the larger species of Crustacea, such as crabs.

Detailed explanation-5: -Compound eyes are organs of vision in arthropods (insects and crustaceans).
