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 hemp-agrimony, Eupatorium cannabinum. In most of their range, the aposematic adults have red underwings. In the northwest part of their range, the adults are polymorphic for underwing colour, being variously red, orange, or yellow.
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... Wikipedia →

Possible
About 20% of wildlife watchers report a Jersey Tiger sighting in Mercantour National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 152nd most-seen of the 412 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August
In that month about 30% of wildlife watchers report a Jersey Tiger in Mercantour National Park on a given day, against under 5% in October to June, the lowest months. That is one of Mercantour National Park's driest months, with about 50 mm of rain against 140 mm in October.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Jersey Tiger sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 13
Of the 13 parks where we can rate Jersey Tiger sightings, Mercantour National Park ranks 8th at about 20%. The best odds are in Plitvice Lakes National Park (Croatia, about 40%), Picos de Europa National Park (Spain, about 40%) and Aigüestortes National Park (Spain, about 40%).
Same family: Erebidae
The closest relatives of the Jersey Tiger that you can see in Mercantour National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Burnet Companion (about 20%), Speckled Pellicle (about 20%) and Scarlet Tiger (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Jersey Tiger is recorded against all the insects logged in Mercantour National Park (13 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
