One of the caterpillars of the Great Duffer (#C16a) has pupated while the other one (#C16b) think it is not time yet and decided to continue eating. #C16b is now about 83mm long!
The pupa of the Great Duffer is pink in color, the same shape but slightly fatter than the pupa of the Palm King (see photo below).
The photo below shows a closeup view of the Great Duffer caterpillar feeding. Isn't it cute ? ;-)
