Abstract
In several pterygote insects, the endocuticle which is secreted by the epidermis after molt grows in a daily rhythm [1,2]. Each day, two layers are formed which differ in the orientation of chitin microfibrils. In the one layer they are helicoidally, in the other one unidirectionaily arranged. In some cases it has been proved that this growth rhythm is controlled by an endogenous circadian clock [2]. In cockroaches this clock exhibits two characteristic features of circadian oscillators -frequency (~1 d-1) and temperature compensation -, but it lacks the third main feature: phase-dependent light sensitivity [3,4]. — The circadian growth of the endocuticle raises two problems: (1) What is its biological significance? (2) Where is the clock localized which controls this developmental rhythm?
