The larva reaches about 30 mm before turning a darker brown. It will wriggle about, causing a split in its old skin at the back of the head.

Further wriggling will push the old skin backwards, exposing the white pupa. The old skin collects as a crumpled mass at the posterior end (above) or as an intact cast (below).

The newly emerged pupa is white, 14×5 mm and curved, turning brown with time
