A system of regular, radial ridges, spaced approx. 250 nm apart, is reported from the outer corneal surface of the eye of the tiny moth Leucoptera coffeella. Antireflective coatings in larger insects with flatter facets often take the form of corneal nipples. However, evidence is presented that in an insect whose eyes have to operate near the lower diffraction limit and possess strongly convexly-curved corneae a radial arrangement of microridges is just as effective as nipples--and simpler to construct.
据报道，在微小蛾类咖啡潜叶蛾（Leucoptera coffeella）的眼角膜外表面存在一种规则的放射状脊系统，这些脊间隔约250纳米。在具有较平小平面的较大昆虫中，抗反射涂层通常呈角膜乳头的形式。然而，有证据表明，对于眼睛必须在接近较低衍射极限下运作且角膜具有强烈凸曲面的昆虫而言，微脊的放射状排列与乳头一样有效，而且构建起来更简单。
