Just like most mantids, coronatus molt upside down when the time comes. The nymphs will refuse food a day or two prior to molting and attention should be given to the humidity to ensure a proper molt. Females will take 7 molts to reach adulthood and males will molt only 6 times...which is why it is very important to slow the males down while speeding up the growth of the females. As long as proper humidity is maintained, there should be no problems with molting. Allow the mantid to dry out on its own and resume feeding 1 day after molting.
