Nyctemera adversata (SCHALLER) (Arctiidae, Lepidoptera) ranges from the Temperate Zone to the tropics in Asia. For N. adversata, the developmental zero and the total effective temperature were obtained under twodifferent conditions, e.g. in solitary and mass-rearing. In mass-rearing, they were 11.1°C and 61.2 day-degrees for eggs, 5.2°C and 299.5 day-degrees for larvae, 12.5°C and 16.3 day-degrees for prepupae, and 10.0°C and 116.6 day-degrees for pupae. In isolation, they were 6.1°C and 340.3 day-degrees for larvae, 14.1°C and day 13.5day-degrees for prepupae, and 7.8°C and 159.7 day-degrees for pupae. When they were reared in isolation at a temperature of 30°C, all larvae passed five instars but one. The exceptional larva had six instars. Both the developmental zero and the total effective temperature of each developmental stage slighty differed depending on feeds. They were 7.0°C and 291.2 day-degrees for larvae, 14.4°C and 10.7 day-degrees forprepupae, and 9.2°C and 137.9 day-degrees for pupae when the moths were fed on Crassocephalum crepidioides (BENTH). S. MOORE. On the other hand, if they were fed on Erechtites hieracifolia (L.) RAFIN, these observations were 5 .8°C and 319.8 day-degrees for larvae, 14.4°C and 10.7 day-degrees for prepupae, and 9.7°C and 129.7day-degrees for pupae. Most individuals passed five insters if they were reared at temperatures of 20°C and 25°C with C. crepidioides. One individual for each temperature had six instars, however. In 1999, seven peaks of appearances of adult moths were recognized by sight-recordings in the field: late May, mid-June, early July, early and late August, mid-September, and mid-October. The number of generationswas estimated to be around 7 or 8 per year by using the total effective temperature.
