They are nature’s flying nocturnal artworks, short-lived, some well-known but others secretive and little-known, often overseen and attracted to light. The adults do not feed at all, and the larvae – caterpillars – are very selective regarding their food plants. A few species are a valuable food source for humans, such as the so-called “mopane worms”, whereas of some species the caterpillars and food plants are not yet known.
