Zygaenid Moth  (Zygaenidae Chalcosiinae Trypanophora semihyalina argyrospila - Walker, 1864)

Found as a larva in Choi Sai Woo Park, North Point, Hong Kong on June 10, 1999.  Several more were found in May, 2000. Larval foodplant seemingly most preferred is Lagerstroemia indica (Crape-myrtle), though it has also been found on Hibiscus, Bauhinia, and Liquidamber.  A 2nd instar larva was found the first week of April, 2002 in Shau Kei Wan.

A  young larva, about 7 mm / 0.3 inch long.

The mature larva was about 23 mm / 0.9 inch.

The larva preparing to spin its cocoon.
The cocoon was typical for a Zygaenid moth, white in color.

These two larva have been parasitized by a small wasp species.
The lighter color of the one on the right may be due to unemerged wasp
larvae inside the caterpillar.  Two such light colored larvae were found; both were parasitized.
