Study Notes
Cicada Lifecycle
- Cicadas go through a remarkable lifecycle with fascinating transformations.
- The lifecycle of a cicada includes egg, nymph, and adult stages.
Egg Stage
- Female cicadas lay eggs in tree branches.
- Eggs hatch after a few weeks, giving rise to nymphs.
Nymph Stage
- Nymphs are wingless and resemble small versions of adult cicadas.
- Nymphs immediately drop from trees to the ground, where they burrow into the soil using their strong front legs.
- Nymphs attach themselves to tree roots and feed on sap, growing larger and molting several times as they mature.
- The nymph stage lasts for either 13 or 17 years, depending on the brood.
Adult Stage
- Cicada nymphs emerge from the ground as fully grown adult cicadas in large numbers, known as a "cicada emergence" or "cicada swarm."
- Adult cicadas shed their exoskeletons, revealing their wings and vibrant colors.
- Adult cicadas have large, transparent wings, which they use to fly to the tops of trees.
- The adult stage of a cicada's life is relatively short, lasting only a few weeks to a few months, depending on the species.
Mating and Reproduction
- Adult cicadas spend their short lives mating and reproducing.
- Male cicadas produce loud buzzing noises by vibrating special structures called tymbals located on their abdomen, serving as mating calls to attract female cicadas.
- Once mating occurs, female cicadas lay eggs in the branches of trees, starting the lifecycle anew.
Death and Decomposition
- After mating and laying eggs, adult cicadas eventually die.
- Their bodies decompose, returning valuable nutrients to the soil, which enriches the surrounding environment.
- The cycle then repeats as the eggs hatch, and new nymphs burrow into the ground to begin their journey underground.
