EARLY STAGES

OVUM:

LARVA: Full-fed 110mm, width 12mm, horn 15 mm. According to Bell & Scott (1937), in the final instar head rounded-triangular, with a small tubercle on the vertex of each lobe. Surface of head moderately shiny, covered with small tubercles. Body shaped as in others of the genus. Horn long, straight, thick at base, and tapering evenly to a strongly, widely bifid tip. Surface of body dull, with an encircling row of large pointed tubercles on each secondary ring. There are seven oblique lateral stripes formed of larger pointed tubercles. Horn covered with large pointed tubercles.

Head grass-green, with a broad whitish stripe separating face from cheek; the tubercles whitish. Body bright yellowish-green above the spiracles, the tubercles in this area yellow, sometimes with reddish tips. The area below the spiracles and venter watery-green with white tubercles. These two areas sharply separated by a well-defined, bright yellow, subspiracular stripe on segments 2 to 4, this stripe edged below by chocolate, and sometimes continued back to 12. The oblique lateral stripes formed of yellow or red tubercles, each running across three segments. Horn bright green, with tubercles of the same colour (Bell & Scott, 1937).
