Jersey Tiger

Euplagia quadripunctaria is widely distributed in Europe from Estonia and Latvia in the north, to France and southern Great Britain in the west, and the Mediterranean coast and islands in the south. It is also found in western Russia, the southern Urals, Asia Minor, Rhodes and nearby islands, the Near East, Caucasus, southern Turkmenistan, and Iran. Individuals are known to migrate northwards from their regular breeding grounds during the summer.

British Isles. Aside from being frequent in the Channel Islands (whence its common name comes), this species was rarely seen in the British Isles in Victorian times. In 1903, it was described by William Forsell Kirby as "a great rarity in the South of England, except one locality in Devonshire". Since then however it has spread more widely in Devon and Cornwall, and became more frequent in southern England by 2014, especially on the Isle of Wight, in northern Kent, and south London. By 2019, it was widespread and common across southern England, and with scattered records north to the Midlands and East Anglia. The increase has continued since then, with a 78% increase between 2024–2025 alone, and consolidation in East Anglia, the Midlands, and into South Wales.
