butterfly

The fore wing span varies between 31 and 43 millimeters in males and between 40 and 49 millimeters in females. There is no sexual dimorphism between the sexes , males and females show almost identical drawing elements . The basic color on the wing tops is milky white. Depending on the incidence of light, they shimmer slightly green, bluish or yellowish. All edge areas are colored black-brown. There is a white band of spots on the submarginal region , which is delimited by a broad black line in the direction of the post-disk region . The cell is bordered by black lines, the lower of which is extended towards the submarginal region, but does not always reach it. A reddish eye-spot and two tail processes stand out at the anal corner of the hind wings. The undersides of the wings shimmer in silver-white, yellow-green or pale turquoise tones. The line drawing is more pronounced and clearer than on the upper sides.

Similar species

Polyura eudamippus lacks the lower line drawing of the cell and the reddish eye spot at the anal corner.

Distribution, subspecies and habitat

Trema orientalis, a food plant of caterpillars

The species occurs in India , Myanmar , Thailand , Laos , Tibet , Vietnam and southeast China . Six subspecies are currently classified in the various occurrence areas . Polyura narcaeus prefers to colonize evergreen deciduous forests. The altitude distribution ranges in locations of up to 2450 meters.

Way of life

The moths fly in two generations a year. They sometimes suck on the ground at damp places in the earth to absorb liquids and minerals. The caterpillars feed on the leaves of the Trema orientalis , a plant belonging to the hemp family (Cannabaceae), as well as on the leaves of hackberry trees ( Celtis ) or Pithecellobium and Prunus species.
