Why are moths marked on the inside of their wings?

Moths often have markings on the inside of their wings that serve various purposes, primarily related to camouflage and communication. These markings can help them blend in with their surroundings when they rest, making it harder for predators to spot them. Additionally, some species use these markings during mating rituals to attract potential mates or signal their readiness to reproduce. Overall, these adaptations enhance their survival and reproductive success in the wild.
