Cicadas are fascinating insects that have been a part of the ecosystem for millions of years. These insects are known for their distinctive songs, which they use to attract mates and defend their territory. In Illinois, cicadas are a common sight, and their presence can be both a nuisance and a wonder. But what attracts cicadas to Illinois, and how can you control their population if they become a problem?
Life Cycle of Cicadas
Cicadas have a unique life cycle that involves a long period of underground development, followed by a brief adult stage. The life cycle of cicadas typically takes 2-5 years, although some species can take up to 17 years to complete their cycle. During this time, the cicadas undergo several stages of development, including egg, nymph, and adult stages. The adult stage is the most visible and audible stage, as the cicadas emerge from the ground and begin to sing and mate.
Cicada Species in Illinois
Illinois is home to several species of cicadas, including the Periodical Cicada (Magicicada spp.) and the Annual Cicada (Tibicen spp.). The Periodical Cicada is the most common species in Illinois, and it is known for its distinctive 17-year life cycle. The Annual Cicada, on the other hand, has a shorter life cycle and is more common in urban areas.
| Species | Description | Life Cycle |
|---|---|---|
| Periodical Cicada | Large, black body with red eyes | 17 years |
| Annual Cicada | Smaller, green body with brown eyes | 2-5 years |
Cicadas are attracted to Illinois due to the state's diverse landscape and climate. The state's deciduous forests, urban areas, and agricultural fields provide a perfect habitat for cicadas to thrive. The insects are also drawn to the state's warm and humid climate, which allows them to complete their life cycle.
What Attracts Cicadas to Illinois?
Cicadas are attracted to Illinois for several reasons, including:
- Food availability: Cicadas feed on plant sap, and Illinois's diverse vegetation provides an abundance of food sources.
- Shelter: The state's forests, trees, and shrubs provide shelter and protection for cicadas from predators and harsh weather conditions.
- Water availability: Cicadas need water to survive, and Illinois's numerous lakes, rivers, and streams provide a reliable source of water.
- Climate: Illinois's warm and humid climate allows cicadas to thrive and complete their life cycle.
Control Methods
If cicadas become a problem, there are several control methods that can be used to manage their population. These methods include:
- Physical removal: Cicadas can be removed physically by hand or using a vacuum cleaner.
- Insecticides: Insecticides can be used to kill cicadas, but they should be used with caution to avoid harming other beneficial insects.
- Traps: Traps can be used to capture and remove cicadas from the area.
- Biological control: Natural predators, such as birds and spiders, can be used to control cicada populations.
In conclusion, cicadas are an integral part of the ecosystem in Illinois, and their presence can be both a nuisance and a wonder. By understanding what attracts cicadas to Illinois and using effective control methods, individuals can manage their populations and minimize their impact on the environment.
