This species is very similar to T. friedeli , but can be distinguished by the following characters: forewing with a kidney-shaped spot in the discal cell; saccus basally constricted; aedeagus slightly bent near the apex; long processes on anterior margin of 8th sternite closer together Specimens examined.

(MWM). Bionomics. The larvae feed on Ficus carica Linn., 1753 , Ficus microcarpa Linn., 1781 , Streblus spp. and Artocarpus heterophyllus Lam., 1789 (all Moraceae ). Adults are on the wing throughout the year in Taiwan (Plate 5B–5E) and Guangdong (Plate 5F). Lin (2005) recorded that young larvae are gray with large subdorsal black spots on A2, and a short fleshy curved horn on A8. Mature larvae were dull brown, mottled paler dorsally and dark brown laterally, and with a purplish-brown double dorsal hump on A2 and a similar but smaller one on A5 (Plate 5G). The cocoon is boat-shaped, closely woven with white or yellow, rather-papery silk (Plate 5H). The pupa is pale yellow and thinly chitinized (Holloway, 1987). The pupa of T. varians is often parasitized by tachinid flies (Plate 6A–6D). Distribution. Mainland China (Guangdong, Guangxi, Yunnan), Taiwan and Hainan Islands, southern Japan , Philippines , Malaysia , Indonesia , Vietnam , Thailand , Nepal , India including the Andaman islands, Sri Lanka . Remarks. Holloway (1987) reported that this species was widely distributed in the Oriental Region. It is an important pest of ornamental plants (Huang et al. , 2002; Rajavel & Shanthi, 2007), and so its biological characters and control have been the subject of several recent works (Ou et al. , 2006; Hussain et al. , 2009).
