Thalassodes immissaria is a moth of the family Geometridae first described by Francis Walker in 1861. It is found in the Oriental tropics of China, India, Myanmar, Sri Lanka, [1] Hong Kong, Japan, [2] Borneo, Vietnam, Sumatra, Sulawesi and the Ryukyu Islands. The populations in Ryukyu were often classified as a subspecies - Thalassodes immissaria intaminataInoue, 1971. [3] However, in 2005 this subspecies was upgraded to a distinct species, which can be distinguished from immissaria by careful examination of the male genitalia. [4]
It is a green moth with faint white lines. There is a very narrow yellowish line border on the wings. Male have plumose (feather-like) antennae, female has filiform (thread-like) antennae. [5] It is very similar to other congener species, therefore identification should done through examination of genitalis. In the male, the genitalia possess a long, tongue-like valva basal process and a tongue-like harpe. [6] The caterpillar feeds on Mangifera indica , Lagerstroemia , Nephelium , Eucalyptus camaldulensis , Dimocarpus longan and Litchi chinensis . [7] [8]
