ocellus
Insect's light sensor
An ocellus is a simple eye found in insects and other invertebrates, distinct from compound eyes—typically appearing as a small spot sensitive to light.
The term also refers to an eye-like marking on an animal, such as the spots on a peacock's tail feathers or a butterfly's wings: The moth's ocelli startled predators.
Plural: ocelli.
