Kudremukh National Park is treasure trove for animal watchers. Entering into the Malleshwara township inside Kudremukh National Park on that day we spotted a cicada sitting on a moss covered tree branch. As I was photographing the cicada which was sitting higher up in the branch I noticed from the corner of my eye a dry leaf fluttering. It was unusual shaped dry leaf on a moist moss covered tree branch. On close inspection it turned out to be well camouflaged The South Indian Blue Oakleaf (Kallima horsfieldi) butterfly. I used my Canon EOS 5D mark II with Canon EF 100mm f/2.8L Macro IS USM to capture this using natural light.

Because of this highly camouflaged wings both in color and shape like Leaf it is highly difficult to identify in low lit rain forest. They take to wings with the least disturbance, and splashing blue colors of the upper side of wings are really amazing. Once they settle in any other branch even near by to you it is difficult to trace, simply they vanish in the nature. This method of rendering invisible is the adaptation of the insect which resembles some special object to which an enemy is indifferent. These butterflies present various types of color and pattern which closely resembles a dead leaf. When it is chased by a bird, it flies and perch on a branch or a trunk of tree, upside down. Then, it flutters its body, as if it is a dry leaf of the tree is moving due to the wind, completely making the bird perplexed, and the bird, fly’s away unable to locate it. Military has used this oak leaf pattern as a successful camouflage starting from WWII German SS “Oak Leaf” camouflage to the present day camouflage.
