Hormones also coordinate the sequence of events in the growth and molting cycle and in some species ensure that an adult emerges when environmental conditions are suitable. The hormones act by regulating genetic activity. In a particular hormonal milieu, the genes that are active are responsible for expression of larval characters; under other hormonal conditions genes for pupal or imaginal features are activated.
