This type of compound eye is normally found in nocturnal insects because it can create images up to 1000 times brighter than equivalent apposition eyes, though at the cost of reduced resolution.In the parabolic superposition compound eye type, seen in arthropods such as mayflies, the parabolic surfaces of the inside of each facet focus light from a reflector to a sensor array. Long-bodied decapod crustaceans such as shrimp, prawns, crayfish and lobsters are alone in having reflecting superposition eyes, which also have a transparent gap but use corner mirrors instead of lenses.
