As far as I am aware no description of the larva, of this insect has been published, and hence I present the following:-

T. pudens.—Mature larva. Head white, with four black spots, two covering the eyes and the others near the summit of the head. A few short, whitish hairs. Body semitransparent, whitish, flecked with opaque white spots on the dorsum and more thinly on the venter. Stigmatal space covered by a blackish shading, more distinct anteriorly; a darker dorsal line. Spriacles pale brown. Cervical spot whitish, concolorous with body. A few short pale hairs.
