A forest filled with rhythmic ticking noises is generally an indicator of Cicadiem activity. Researchers closely monitor the ticking to determine particular Cicadiem broods and how far along they are until emergence.
Juvenile Cicadiem, using their spiked back that is reminiscent of a sundial, will emerge by the hundreds to even thousands from a tree's many branches and fall to the forest floor, where they will then dig into the root system to feed before pupating. Cicadiem remain in this pupal stage until it is time to emerge from the soil as fully-matured adults, often decades later, and repeat their life cycle.
Their mating call is comparable to that of the metallic ringing of an alarm clock.
