The larvae entered the third instar the following day, and 24 hours later measured 13-14.5 mm in length.
The larvae again moulted and entered the fourth instar two days later, and were now between 12-17 mm in length. They were now a much lighter green which corresponds very accurately with the colour of the leaf upon which they rested. Close examination still revealed the presence of tiny black specks on the upper body of the larvae. At the end of this, the fourth and final instar, the larvae were recorded as being 23 to 28 mm in length and were eating voraciously. Pupation took place during the night.
When the larvae pupate on their foodplant in their natural surroundings, pupation always takes place on the underside of the leaf. The pupa are pale green approximately 23 mm in length and closely resemble the colour of the underside of the leaves. Under artificial conditions some of the larvae pupated on wood, which resulted in their being a lilac colour as previously observed by Colonel Burkhardt.
It is of importance to note, that the osmeterium was also quite frequently observed during the various stages, and is recorded as being translucent.
