Nocturnal insects possess in general superposition compound eyes. This eye design is truly optimized for dim light as photons can be gathered through large apertures comprised of hundreds of lenses. In apposition eyes, on the other hand, the aperture consists of a single lens resulting in a poor photon catch and unreliable vision in dim light. Apposition eyes are therefore typically found in day‐active insects. Some nocturnal insects have nevertheless managed the transition to a strictly nocturnal lifestyle while retaining their highly unsuitable apposition eye design. Large lenses and wide photoreceptors enhance the sensitivity of nocturnal apposition eyes. However, as the gain of these optical adaptations is limited and not sufficient for vision in dim light, additional neural adaptations in the form of spatial and temporal summation are necessary.

Introduction Insects with apposition eyes are generally day‐active since this eye design has significant limitations in dim light. Apposition eyes have small lenses and therefore a poor photon capture, resulting in unreliable visual signals at low light intensities. Nevertheless, some insects have managed the transition from a diurnal to a nocturnal lifestyle while retaining apposition eyes.
