Cicadas, commonly known as "locusts" or "jarflies," are insects that belong to the family Cicadidae. Cicadas are known for their loud and distinctive buzzing sound, which is made by the males to attract females. In this article, we will discuss when cicadas appear and some interesting facts about these fascinating insects.
What are Cicadas?
Cicadas are insects that live underground for most of their lives. They are known for their loud buzzing sound and their unique life cycle. Cicadas are not harmful to humans, but they can cause damage to trees and plants.
Life Cycle of Cicadas
Cicadas have a unique life cycle that spans several years. Depending on the species, cicadas can live underground for anywhere from two to 17 years. During this time, they feed on the sap of tree roots and undergo several molts. When it is time for them to emerge from the ground, they climb to the surface, shed their skin, and become adults.
When Do Cicadas Appear?
The timing of cicada emergence depends on the species and the location. In general, cicadas emerge in late spring or early summer, when the soil temperature reaches a certain threshold. In the United States, the periodical cicadas emerge every 13 or 17 years, while the annual cicadas emerge every year.
Where Do Cicadas Appear?
Cicadas are found all over the world, but they are most common in tropical and subtropical regions. Some species of cicadas are found in the United States, including the periodical cicadas, which emerge in large numbers in the eastern and central parts of the country.
Why Do Cicadas Appear?
The primary reason cicadas appear is for mating. The males produce a loud buzzing sound to attract females. When a female finds a male, they mate and lay eggs in the bark of trees. The eggs hatch into nymphs, which burrow into the ground and begin the cycle anew.
