Hi Soon Chye,

Your photo 27 almost certainly shows caterpillars of the Great Duffer, Discophora timora, not Common Duffer. In comparison, young larvae of the Common Duffer are banded black and white (http://nc.kl.edu.tw/bbs/showpost.php...0&postcount=38), while mature cats are patterned somewhat differently and have a dark head capsule (http://nc.kl.edu.tw/bbs/showpost.php...6&postcount=21).
