TELL ME WHY

You must have seen moths being attracted to lights. Do you know why' Well, the poor fellows mistake the lights to be the moon which they use to navigate their routes. These lights confuse the moths and make them lose their sense of direction. As these insects are extremely responsive to ultraviolet rays, collectors use these rays to trap them. But since they cannot see red or yellow light, it is possible to watch these insects feed without disturbing them, by using a red light.
