 Though not universal, moths very commonly have superposition eyes, while butterflies equally commonly favour apposition eyes.This is due to the superposition eye's adaptations for low light environments suiting the nocturnal moths, and the apposition eye's superior resolution and potential for colour vision benefiting the more diurnal butterflies.There are several exceptions to this rule, such as with the diurnal Zygaenidae and Sytomidae families of moths, both of which have apposition eyes, or the Hedyloidea family of butterflies, which are nocturnal and feature superposition eyes.
