Larva. 1st stage. Chocolate-brown, each segment with a transverse yellow stripe ; 

 three yellow spines on thoracic segments, and a yellow bifid tail consisting of two 

 yellow divergent spines. The larva does not exceed \ inch in length in this stage.

 lower portion, which is violaceous grey. Three thin black spines with scarlet bases on 

 thoracic segments. Head ferruginous, thoracic legs and claspers pale grey.
