The actual molting intervals is likely to be different from species to species. The cuticle supporting the arthro-pod legs acts as a spring, efficiently storing and releasing energy as the animal moves.

The result can be mutilation or a form of suffocation. Molting Arthropod cuticle cannot grow along with the animal, so an arthropod must shed its exoskeleton in a process called molting. Ladybugs are known to exhibit this behavior, for example. At unfavorable conditions (during times of environmental stress) the X-organ will secrete the molting inhibiting hormone, and the molting process will cease. While molting serves as an essential role for insect growth and transformation, it is also potentially the most dangerous part of an insect’s life.
