The garden tiger moth is found throughout Europe as far north as Lapland, in Asia, and in North America. In the mountains this species is found up to an elevation of 2,000 metres (6,600 feet). The garden tiger moth loves damp places, which is why it is particularly common in river valleys as well as gardens and parks. The moth is nocturnal and can usually only be seen flying around a source of light. The distinctively coloured, long-haired caterpillar, on the other hand, is seen more frequently. Itc can grow up to 6 cm (2½ inches) long and plays dead when in danger.
