Saturniidae are commonly known as emperor moths or simply just as silkmoths. The group includes about 2000 described species, found mostly in tropical countries.
These beautiful moths are often very large and many have eyespots on the hindwings for frightening predators.
They do not feed as adults but rely solely on fat reserves built up when they were caterpillars and so live for only a few days.
Emperor moth caterpillars are frequently brightly coloured and covered in poisonous spines.
