Species: Kallima inachus (Doyère, 1840)
Common name(s): The Orange Oakleaf, The Dead Leaf, The Indian Leaf Butterfly
Photography location: Tam Dao foothills (Vinh Phuc Prov.)
This powerful flier is often seen in dense forests, amongst undergrowth and along stream beds. It is attracted to tree sap and over-ripe fruit, and is also known to mud-puddle.
Much pursued by birds, when in danger the Orange Oakleaf flies erratically, soon dropping down into the foliage and occupying a stationary pose with wings closed, so that the birds are very often quite unable to find them. In such a pose, the butterfly resembles a dried leaf and is perfectly camouflaged.
With wings closed, it closely resembles a dry leaf with dark veins and is a spectacular and commonly cited example of camouflage.
