The eggs are
laid singly on the upperside of leaves of
Citrus, Zanthoxylum and other
Rutaceae. The slug-shaped caterpillar is dark translucent green,
with a pair of narrow yellow lines running dorso-laterally. It has a
brown head which is heart-shaped when viewed from the front. It
lives solitarily in a nest made of silked leaves. The pupa is dark
green, covered in a pale green waxy secretion.
Males are usually seen as
singletons amongst mixed mud-puddling aggregations of other Pyrgine
skippers. They can also be seen perching on the foliage of bushes,
which they use as "look out posts" to survey passing females.
Both sexes rest and
feed with the wings outspread.
