Found 2 moth specimens at rest in North Point, Hong Kong the last week of September, 1999. Another fresh female was found on September 25, 2001 in Shau Kei Wan, Hong Kong. The 2 mature larvae pictured below were found at Fairview Park, Yuen Long, Hong Kong on October 20 and November 7, 1999. They were feeding on Vinca (Periwinkle). Four larvae were found in the first week of January, 1997, near the North Point ferry terminus, also feeding on Vinca. Three were in the final instar. Another mature larva was found October 7, 2002 at Fairview Park, feeding on Apocynaceae Adenium obesum (Desert Rose), reportedly the main foodplant in Africa. As the name implies, it also feeds on Oleander. A mature larva, three 1st-instar larvae and 2 ova were found October 22, 2002 in Shau Kei Wan, Hong Kong on Vinca. Also in Shau Kei Wan, two mature larvae were found on January 2 and two 3rd instar larvae on January 8, 2003, on Vinca.

An example of a green larva, 84mm / 3.3 inches long.
The instensity of the blue-green eye-spots can vary.
Note the changing appearance of the tail horn; instar stage
can be determined from these consistent changes.
The mature larva may occur in the 4th or 5th instar.
The brown form of the mature larva.
This form is not common and seems only to occur with the final instar change.
This was only the second brown one found since 1997.
