There are the caterpillars of the Sphingidae family which attacked one of the plants in the backyard in Jonggol, West Java, some time ago (see Caterpillars Attack My Plant).
One afternoon, one of them I saw walking towards other plant nearby, then it hid behind one of the leaf.
After not doing anything for almost 1 day, the caterpillars finally began to molt at noon the next day. This is my first experience of seeing a caterpillar molting process.
After the entire process was completed, the caterpillars eat the old skin.
Note: Caterpillars of the Sphingidae family are often called hornworms due to the well-developed "horn" on the posterior end of the abdomen.

Photos of Moth Caterpillar (Sphingidae family) molting process were taken using a camera phone Sony Ericsson K800i in Jonggol, West Java, Indonesia.
