Tussock moth  (Lymantriidae Calliteara horsfieldii - Saunders)

Found as a mature caterpillar on an Acacia tree at Braemar Hill, North Point, Hong Kong on December 6, 1998.  I found another specimen on its foodplant, Evodia lepta, in the same area on December 20, 1998, but it turned out to have been parasitized by flies.  A nearly mature larva found on April 26, 2002 in Shau Kei Wan was feeding on Ficus .

Lymantriidae caterpillar
The mature caterpillar was about 40 mm / 1.5 inches long.
The dark neck band was a dark reddish-purple color.

The cocoon had three layers of silk, the outer, spiney layer,
a second buffer layer which had some spines, and a final inner layer of silk.
