Colonel C. T. Bingham wrote of the genus in 1878;-

The Melanitis was there among dead leaves, its wings folded and looking for all the world a dead, dry leaf itself. With regard to Melanitis, I have not seen it recorded anywhere that the species of this genus when disturbed fly a little way, drop suddenly into the undergrowth with closed wings, and invariably lie a little askew and slanting, which still more increases their likeness to a dead leaf casually fallen to the ground.

Special feature:  The Burmese python (Python bivittatus) is one of the five largest snakes in the world, native to a large variation of tropic and subtropic areas of Southern- and Southeast Asia. Until 2009 they were considered a subspecies of Python molurus, but now are recognized as belonging to a distinct speciesThey are often found near water and are sometimes semi-aquatic, but can also be found in trees. Wild individuals average 3.7 metres (12 ft) long, but have been known to reach 5.74 metres (19 ft).  This python is an excellent swimmer and needs a permanent source of water. It can be found in grasslands, marshes, swamps, rocky foothills, woodlands, river valleys, and jungles with open clearings. They are good climbers and have prehensile tails.
Wild populations are considered to be "threatened" and are listed on Appendix II of CITES. IUCN has recently listed the Burmese python as "Vulnerable", reflecting its overall population decline. Important reasons for the decline are trade for skins and for food; habitat degradation may be a problem in some upland areas. In Hong Kong, it is a protected species under Wild Animals Protection Ordinance Cap 170. (Wikipedia)
  
When compared with Indian Rock Python : 
 by Vivek Sharma    (ReptileIndia)
Burmese Pythons have side patches (on flank) more defined and much larger than those found in Indian Rock Python. In Indian Rock Python they are very small and usually not much significant to discuss. Additionally Burmese Python has much less or no yellow-brown amounts on body while in Indian Rock Python you can find these two colors have much significance.

The caterpillars are a striking dark brown color with yellow triangles along each side and metallic blue protrusions along the dorsal surface. They feed on vines until they are ready to spin their wild silk cocoons. Cultivating silk moths for fabric production has a long history starting in 2700 B.C. with the Chinese. They kept their secret until 300 AD, when their techniques spread to Korea and Japan (http://www.insects.org).


They have a short adult life, less than a week and it feeds on food that had been stored during there caterpillar days.
