details of buterfly eye
Answers
Answer:
Butterflies have compound eyes. Rather than our one big eye, they have up to 17,000 mini eyes each of which has its own lens, a single rod, and up to three cones. Where we have cones (photo-receptors) for three colors, butterflies have photo-receptors for up to nine colors, one of which is ultra-violet.
Explanation:
Butterflies have two eyes just like we do. But butterfly eyes are called compound eyes because they have many, many lenses. That means butterflies can see many different things in many directions all at the same time. ... Most butterflies can see red, yellow, blue, and green, but some species can see other colors, too.
Butterflies use colour vision when searching for flowers. Unlike the trichromatic retinas of humans (blue, green and red cones; plus rods) and honeybees (ultraviolet, blue and green photoreceptors), butterfly retinas typically have six or more photoreceptor classes with distinct spectral sensitivities.
