The species of emerald moth that infested litchi and longan was identified as Thalassodes immissaria(Walker) not as identified as Pelagodes proquadraria(Inoue) before by field survey and analysis of male genitalia.The biological charac-teristics and occurrence pattern of T.immissaria were studied.The larva of T.immissaria can be divided into 5 instars based on Dyar’s law.Adults showed sexual dimorphism,which the antenna of female moth was filiform and that of male moth was plumose.T.immissaria made damage to litchi and longan young leaves and twigs by larvae and occurred 7 to 8 generations a year in Guangdong province.The full-grown larva spun silk to combine the leaves around itself and turned into pupa in the combination.Eggs were laid singly in finial and edge of young leaves.Under the laboratory condition,the developmental du-ration of egg,pupa,1st to 5th instar larva and pre-oviposition was 3.64,6.67,2.76,2.80,3.42,3.89,5.16,and 1.63 d respec-tively at 26 ℃.
