Sugi (1987) illustrated the larva. It appears to be identical to that illustrated for T. coronata Fabricius and described below.

The host-plants noted by Sugi, by Miyata (1983) and by Robinson et al. 2001) were Castanea, Quercus (Fagaceae), Juglans and Pterocarya (Juglandaceae).

The adult is a fruit piercer in Thailand (Bänziger, 1982; Kuroko & Lewvanich, 1993).
