Jersey tiger, Spanish flag
Euplagia quadripunctaria, the Jersey tiger, or Spanish flag, is a diurnal moth of the family Erebidae. The species was first described by Nikolaus Poda von Neuhaus in 1761. The adult wingspan is 52–65 millimetres (2.0–2.6 in), and they fly from July to September, depending on the location. They tend to fly close to Eupatorium cannabinum.
The larvae (caterpillars) are polyphagous, feeding from September to May on nettles (Urtica), raspberries (Rubus), dandelion (Taraxacum), white deadnettle (Lamium), ground ivy (Glechoma), groundsel (Senecio), plantain (Plantago), borage (Borago), lettuce (Lactuca), and hemp-agrimony (Eupratoria). The insect overwinters as a small larva.
Large groups of adults of subspecies E. q. rhodosensis can be found on occasion aestivating (sheltering from the summer heat) in Petaloudes, on Rhodes, in a place that has become known as the Valley of the Butterflies.
Euplagia quadripunctaria is widely distributed in Europe from Estonia and Latvia in the north to 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.
This is the only lepidopteran which has been designated as a 'priority species' under Annex II of the Habitats Directive in the European Union, as of 1992, which means areas in which it occurs can be declared Special Areas of Conservation.
