This common species is native to western Eurasia, but has been introduced to Antigua & Barbuda, Argentina, South Africa, Fernando Pó, São Tomé, Madagascar, Mauritius, Mayotte, Réunion, Seychelles, Comoro Islands, Morocco, Algeria, Tunisia, Cyprus, Israel, Cape Verde, Australia, New Zealand, Canada, the United States, the Falkland Islands and Peru.
