Night-blooming flowers usually depend on moths (or bats) for pollination, and artificial lighting can draw moths away from the flowers, affecting the plants ability to reproduce. A way to prevent this is to put a cloth or netting around the lamp. Another way is using a coloured light bulb (preferably red). This will take the moths attention away from the light while still providing light to see by.
Despite being framed for eating clothing, most moth adults do not eat at all. Most like the Luna, Polyphemus, Atlas, Prometheus, Cercropia and other large moths do not have mouths. When they do eat, moths will drink nectar. Only one species of moth eat wool. The adults do not eat but the larvae will eat through wool clothing.
The study of Moths (and Butterflies) is known as ‘lepidoptery’, and biologists that specialise in either are called ‘lepidopterists’. As a pastime, watching Moths (and Butterflies) is known as ‘mothing’ and ‘butterflying’.
