The name Black Metalmark, Melanis refers to the melanic pigment of the black scales which cover the distinctively shaped wings of all members of this genus. Many Melanis species are marked with orange borders on the hindwings, and / or similarly coloured diagonal bands on the forewings. In some species the apex of the forewings is orange, and in others there are large red spots near the base of the wings.

There are 27 known members in the genus. One particularly attractive species, Melanis pixe, has a range extending from Panama to Mexico and along the Rio Grande Valley in southern Texas. But the majority of species are found in the Andes mountains, or in the Amazonian lowlands.

Slægtnavnet Sortvinge, Melanis refererer til den melanitiske pigmentfarve på skæl, som dækker de markant formede vinger på alle medlemmer af denne slægt. De fleste Melanis arter er med orange sømbånd på bagvinge, og / eller lignende farvet diagonale bånd på forvinge. På nogle arter er apicalplet på forvingespids orange, og på andre er der store røde pletter nær forvinge rodfelt.

Der findes 27 kendte arter i slægten, de fleste arter findes på Andesbjergenes østskråninger fra Venezuela, Colombia, Ecuador, Peru til Bolivia og i Amazonas lavland. En anden art som f.eks. Melanis pixe har en nordligere udbredelse, der strækker sig fra Panama til Mexico og langs Rio Grande dalen i det sydlige Texas.

Smith's Pixie, Melanis smithiae (Westwood, 1851)
Family - Riodinidae
subfamily -
Riodininae
tribe -
Riodinini

Smith's Pixie, Melanis smithiae exhibits local and geographical variation in the extent of the orange markings. The red spots vary in size and are absent on the hindwings of many examples. Wing Span: 1 1/2 - 1 7/8 inches (38 - 44 mm.).

This species is found from Brazil, Peru, Bolivia, Paraguay and further to Misiones in northern Argentina.

Habitats: This species inhabits transitional rainforest / cloud forest in the eastern Andes, at altitudes between about 200-1000m. This species flies throughout the year but is commonest in the early part of the dry season.

Lifecycle: no information available on its way of lifecycle is likely to be similar to that of other Melanis species : The larvae are hairy, and feed gregariously on the leaves of trees in the family Leguminosae. The pupae are said to be formed in clusters on tree trunks.
