Chersotis cuprea

There are three recognised subspecies:

• Chersotis cuprea cuprea
• Chersotis cuprea japonica (Japan)
• Chersotis cuprea schaeferi (Eastern Tibet)

Chersotis cuprea have a wingspan of 32–36 millimetres (1.3–1.4 in) in males, of 33–39 millimetres (1.3–1.5 in) in females. 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 outlined in thin whitish. 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.[1]

The moth flies from July to September depending on the location. The larvae feed on Vaccinium myrtillus, on Asteraceae (Centaurea or Taraxacum) and on other plants.[2][3]

This species can be found in Northern Europe, the Pyrenees, Central Europe down to Greece and east through the Ukraine, Siberia, Turkey, the Caucasus and Armenia, up to China and Japan.[2][4]

These moths live in forests and in mountain forests, in nutrient-poor grasslands and especially in partly humid alpine pastures.[3]
