(K. L. comm.). One member of this plant genus was common and flowering in 

 profusion at Mai Po where we recorded our only sighting of this hawk-moth. The 

 moth was in very good condition, probably freshly emerged, and sitting within the 

 trap in the morning. Tennent (1992, 1993) found the moth fairly widespread but 

 sporadic in Hong Kong, with emergences also noted in October, and reports that 

 both Mike Bascombe and James Young have reared it from J acquemontia paniculate 

 (Burm. f.) Hall. f. (Convolvulaceae). 



Clanis bilineata bilineata (Walk., 1866) 



Tennent made the interesting observation that this species generally comes to 

 light rather late in the night, mainly after midnight (some six hours after dusk 

 in Hong Kong) and that the moth was regularly seen flying between 04.00 hrs and 

 dawn. Our specimen from Long Harbour, Sai Kung, was taken in a light trap that 

 was operated all night. K. L. found a mating pair in copulation on Pueraria 

 lobata (Willd.) Ohwi (Leguminosae), a common climber, on 19 April 1991 on an 

 open slope covered extensively with the larval foodplant, near the Outdoor Recreation 

 Centre, Sai Kung. Previously K. L. had found an adult on 5 May 1988 at the lights 

 of the toilet building at Hok Tau in woodland. K. L. was given a larva found by 

 Professor Shigerue A. Ae on 19 June 1993 on P. lobata at Ng Tung Chai. The larva 

 was feeding on a leaf when found and was 75 mm in length. It pupated on 1 July 

 after a pre-pupation period of seven days and the adult emerged at 20.00 hrs on 

 15 July 1993. 



Leucophlebia lineata Westw., 1847 



The singleton we recorded, in the light trap at Long Harbour, was extremely worn. 

 Tennent (1992) found the moth not at all common in Hong Kong, with adults in 

 April, May and August. 



Marumba dyras dyras (Walk., 1856) 



One of the commonest hawk-moths in Hong Kong (Plate III, Fig. 1), according 

 to Tennent, who reports it being found as an adult in every month from March 

 to October. K. L. found six larvae on the undersides of leaves on several trees of 

 Hibiscus mutabilis L. (Malvaceae) on 8 October 1988 on the Aberdeen Reservoir Road 

 and a larva 25 mm in length on Microcos paniculate L. (Tiliaceae) on 1 May 1991 

 at Pak Long Tsuen. The latter formed a pupa on 1 June and the adult emerged 

 on 24 June 1991. Young (in Tennent, 1992) has also reared larvae on both these 

 foodplants in Hong Kong. The moth turned up every night at Wardhaven, in fresh 

 condition, and was probably breeding nearby. We did not see it at Tai Po Kau. e\ en 

 though Tennent (1992) had 61 individuals there and we had one at nearby Hong 1 ok 

 Yuen, so possibly it flies fairly late and is less likely to be recorded unless the trap 

 is operated most of the night.
