passage between Siberia and Australasia. It consists of coastal mangrove swamp and 

 a system of man-made shrimp ponds or 'geiwais' and fishponds that have been 

 managed for several decades but are now largely abandoned (Irving & Morton, 1988). 

 It is the most extensive area of wetland in Hong Kong and the only substantial 

 area of mangroves remaining. The light trap was operated on a 50 m cable from 

 outbuildings at the education centre adjacent both to reed beds of Phragmites australis 

 (Cav.) Steudel and a large block of mangrove trees, principally Kandelia candel (L.) 

 Druce.

Observations 



The moths were all in generally good condition and appeared to be freshly emerged. 

 Early April in Hong Kong is usually the beginning of the early summer rains. January 

 and February are normally dry, rainfall is light in March but increases through the 

 months from April to October, in any of which from May to October there may be 

 typhoons and heavy rain. In 1993 the weather had been drier than usual, little rain 

 in March, a few showers in early April and we did not encounter heavy rain until 

 the last week of our stay. 



Agrius convolvuli (L., 1758) 



Norman Tong, a friend of Kent Li, has reared this species from larvae collected on 

 an Ipomoea sp. and has reared them in captivity on morning glory Ipomoea spp.
