| Description |
La Belle-Dame est le papillon à l'aire de distribution la plus large au monde : elle peut être observée sur tous les continents à l'exception de l'Antarctique. Elle est commune dans toute l'Afrique, l'Asie et l'Europe, mais son caractère migratoire fait qu’elle n'est résidente permanente que dans peu de lieux. Elle est presque entièrement absente d'Amérique du Sud et d'Océanie. En Australie et dans les îles proches, elle est remplacée par l'espèce voisine Vanessa kershawi. En France métropolitaine, l'espèce n’est pas résidente permanente, mais est présente une partie de l’année (d’avril à octobre environ) en tant que migratrice, et peut être observée dans tous les départements, en abondance très variable selon les années. Aux Antilles, elle est rarement observée, et toujours comme migratrice . .Cardui occurs in any temperate zone, including mountains in the tropics. The species is resident only in warmer areas, but migrates in spring, and sometimes again in autumn. It migrates from North Africa and the Mediterranean to Britain in May and June, but for decades, naturalists have debated whether the offspring of these immigrants ever make a southwards return migration. Research suggests that British painted ladies do undertake an autumn migration, making a 9,000-mile (14,000 km) round trip from tropical Africa to the Arctic Circle in a series of steps by up to six successive generations. The Radar Entomology Unit at Rothamsted Research provided evidence that autumn migrations take place at high altitude, which explains why these migrations are seldom witnessed. |
