摘要: In most apposition compound eyes there are two components to the optical system of ommatidium1,2, cornea and crystalline cone. The focusing power is well documented3,4 whereas cone usually regarded as a mere spacer5,6; consequently, ommatidial optics will consist simple lens. To contrary, we now demonstrate existence complete afocal telescope in each ommatidium butterfly eyes. an extreme variant that found refracting superposition eyes, thereby providing connection between butterflies moths.
