Cicadas are insects related to leafhoppers and aphids. They have a large head with two large compound eyes, short antennae, and a large abdomen. Their wings are clear, and their bodies are usually black or brown. Males have a unique organ that produces a high-pitched, buzzing song that can be heard for miles around.

Why do cicadas emerge in large numbers every 17 years?

Most species of cicadas have long life cycles, with nymphs that live underground and feed on plant roots for many years. The majority of cicadas in eastern North America have a 17-year life cycle. This means that they spend 17 years underground as nymphs, then emerge from the soil as adults, reproduce, and die in the space of a few weeks.

What is the purpose of such a long life cycle?

The long life cycle may help cicadas avoid predators. Since they only emerge once every 17 years, predators are not able to adapt to their presence and are caught off guard when the cicadas suddenly appear in large numbers.

How do cicadas reproduce?

Males sing to attract females. When a female cicada locates a male, they mate. After mating, females dig into the soil to lay their eggs. The eggs hatch 4 to 6 weeks later, and the nymphs immediately start feeding on plant roots.

Do cicadas harm humans?

Cicadas do not harm humans. They can, however, damage trees and shrubs. The nymphs can feed on the roots of trees and shrubs, causing them damage and sometimes even kill them. The adults can also damage plants by laying eggs in the stems. Cicadas are also noisy! In some cases, the sound can be deafening.

What are some ways to deal with cicadas?

There are a few things you can do to deal with cicadas if they are bugging you:

* Ear plugs or headphones. If the noise of the cicadas is driving you crazy, try wearing ear plugs or headphones to block out the sound.

* Screens. You can also use screens to keep the cicadas from getting into your house or car.

* Be careful walking. Sometimes cicadas can blanket sidewalks, making it difficult to walk. Take extra care when walking or driving in areas with a lot of cicadas.

* Be aware. Cicadas are also sometimes mistaken for insects that are actually harmful, such as wasps and hornets. Be aware of the difference so you don't accidentally swat at a harmless cicada.

Cicadas are a nuisance, but they are also fascinating creatures. Their long life cycle and unique behavior are a reminder of the wonders of nature.
