features
butterfly
Vanessa samani is the lightest species of the genus Vanessa and is quite small with a fore wing length of 25 millimeters in the male and 23 millimeters in the female. The basic color of the upper side of the wing is dark ocher yellow and the front wing is darkly pollinated at the base and along the rear edge. The apical part is broadly black, beginning in front of the middle of the anterior margin and strongly indented, extending down to the posterior margin. At the end of the first third of the front edge is a black triangular spot that protrudes with the tip into the central cell. Approximately in the middle of the first median branch there is another black, roundish spot directed towards the rear edge. At the beginning of the last third of the front edge, approximately in the middle of the black apical part, there is an elongated, ocher-yellow spot directed towards the middle of the outer edge. There is a round white spot between it and the outer edge.
The hind wings are dark ocher yellow, blackish along the upper edge, along the outer edge with a series of blackish, triangular spots, of which the last in the anal angle is double and pale silver-blue dusted. Behind this runs another row consisting of four black dots.
The underside of the forewings is similar to the upper side, but is paler. The black of the front half of the wing changes to gray-brown towards the apex . In the black field in front of the elongated yellow spot at the beginning of the last third of the front edge there is a fine blue, curved line.
The hind wings are of almost the same color and markings as Vanessa dejeanii . Only the blue-dusted triangles in front of the outer edge are a little less sharp and the row of eyes and spots behind them are only represented by a row of completely faded points, which in dejeanii are two fully developed, pithead eyes between M1 and M2.
Geographical distribution and habitat
Vanessa samani occurs on the Indonesian island of Sumatra on the Korintji and in the Karobergen at an altitude of 1000 to 1200 meters. Nothing is known about the way of life. Besides the first description by Hagen, there are only two butterflies from 1912.
