Cicadas vibrate special organs called tymbals, B.A., Political Science, Rutgers University. Finally, in September, mating stops. Animals need the right conditions to stay alive. Some larvae will travel longer distances than others. Special cells that were present in the larva are now growing rapidly. The next stage is the larva. Caterpillars munch nutrient-rich leaves to enable all that developmental change, and butterflies just need to sip nectar (essentially sugary water). One of the most common misconceptions is the idea that all living things breathe in the same way.
