Chersotis cuprea is a moth of the family Noctuidae. There are three recognised subspecies: Chersotis cuprea cuprea Chersotis cuprea japonica (Japan) Chersotis cuprea schaeferi (Eastern Tibet) Adult males have a wingspan of 32–36 millimetres (1.3–1.4 in); adult females have a wingspan of 33–39 millimetres (1.3–1.5 in). This species shows a high variability in the basic colors. Usually, the upper side of the forewings is coppery reddish brown (hence the Latin name cuprea) with dark brown markings that have a thin whitish border. The underside of the forewing is dark gray-brown. The hind wings are monochrome gray-brown. Caterpillars are gray-brown, with dark dorsal markings and bright side stripes.
Warren (1914) states R. cuprea Schiff. (= haematitedea Esp.) that the forewing is a dull brown; the median area below the subcostal vein is dark brown; the veins and edges of stigmata are very finely pale; the stigmata are a deep brown; the costa is dark with fine pale speckling and a dark shade before the submarginal line; the hindwing is gray-brown with a yellowish fringe. The species in found in Northern Europe (excluding Britain), Armenia, and Kamschatka... Wikipedia →

Rare
Under 5% of wildlife watchers report a Chersotis cuprea sighting in Pyrénées National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 940th most-seen of the 1277 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
August
In that month about 10% of wildlife watchers report a Chersotis cuprea in Pyrénées National Park on a given day, against under 5% in September to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Chersotis cuprea sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 3
Of the 3 parks where we can rate Chersotis cuprea sightings, Pyrénées National Park ranks 3rd at under 5%. The best odds are in Vanoise National Park (France, about 10%) and Mercantour National Park (France, about 10%).
Same family: Noctuidae
The closest relatives of the Chersotis cuprea that you can see in Pyrénées National Park (family Noctuidae, Cutworm Moths and Allies) are Silver Υ (about 10%), Cotton Bollworm Moth (about 10%) and Marbled White-Spot (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chersotis cuprea is recorded against all the insects logged in Pyrénées National Park (9 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.
