Parides burchellanus

Parides burchellanus is a species of swallowtail butterfly (family Papilionidae). It is endemic to Brazil.

Description
Parides burchellanus is a large, velvet-black butterfly. The forewing is unmarked except for small, white marginal spots. The underside of the hindwing has small, red postdiscal spots. These are smaller and paler on the lower surface. The hindwing has a scalloped outer margin and a large androconial hair-pouch on the anal margin of the male. There are no tails. Apart from the hair-pouch, the sexes are alike. A full description is provided by Rothschild, W. and Jordan, K. (1906)

Biology
The food plants of the larva are Aristolochia chamissonia and A. melastoma.

Habitat and threats
P. burchellanus is a rare species or, if it is a subspecies, an evolutionarily significant unit, of butterfly (Lepidoptera, Papilionoidea) that lives in a very few areas in central Brazil. Its close relation with a highly peculiar environment (gallery or riparian forest along rivers running through the cerrado landscape) restricts its occurrence to a few points. The frailty of its habitat, towards the increasing of loss of natural environments, makes it a target prone to elimination.

The Parides burchellanus is associated with riparian forests in Brazil, in which these rare butterflies tend to inhabit narrow streams among sectors in which the river is cut off by the forest canopy.

Etymology
The name honours William John Burchell.
