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 →

With luck
About 10% of wildlife watchers report a Chersotis cuprea sighting in Mercantour National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 348th most-seen of the 412 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
August
In that month about 20% of wildlife watchers report a Chersotis cuprea in Mercantour National Park on a given day, against under 5% in October to July, 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 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.
Among the best
Of the 3 parks where we can rate Chersotis cuprea sightings, Mercantour National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Vanoise National Park (France, about 10%).

GBIF citizen-science records
It is estimated from how often the Chersotis cuprea is recorded against all the insects logged in Mercantour National Park (5 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.
