Family - NYMPHALIDAE
subfamily - CYRESTINAE
Tribe - PSEUDERGOLINI
Pseudergolis wedah  Darjeeling, India Haraprasan Nayak
Introduction
Some taxonomists elevate the tribe Pseudergolini to subfamily status ( Pseudergolinae ), but in this treatment I adopt the classification of Wahlberg who considers it to be a tribe of the Cyrestinae, i.e. the Mapwings, Maplets and Daggerwings. The tribe comprises of 4 genera - Dichorragia, Amnosia, Stibochiona and Pseudergolis, all of which are Oriental in distribution.
The genus Pseudergolis comprises of just 2 species - avesta, which is endemic to Sulawesi; and the illustrated species wedah, which is found in India, Nepal, Bhutan, Burma, Thailand and China.
Habitats
This species is found in sub-tropical forest at altitudes between about 1500-2300m.
Lifecycle
The larval foodplant is Debregeasia ( Urticaceae ).
Adult behaviour

Both sexes bask either on the ground, or on low foliage. They also settle on twigs, facing head-downwards, to bask with wings outspread. Males commonly settle on rocks, boulders or bare soil to imbibe mineralised moisture, and are attracted to urine and dung. When feeding they generally keep their wings outspread, but hold them erect in hot conditions as a means of thermoregulation.

The butterflies often settle under leaves, and at these times always keep their wings fully outspread - a feature they share with their cousins in the genera Cyrestis and Chersonesia ( tribe Cyrestini ).
