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 -
Pseudergolis, all of which are Oriental in distribution.
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.
This species is found in
sub-tropical forest at altitudes between about 1500-2300m.
The larval foodplant is Debregeasia (
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.
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 ).
