During day-light it remains fixed and motionless on its favourite plant, which it resembles in colour, and thus escapes observation. The chrysalis is smooth, thick, carinated, and of a coriaceous texture, the colour pale green.

These speedily deposit their eggs, which are hatched in June, and after three months occupied in the usual transformations, the second flight appears in September, and continues the race in the manner above mentioned.
