  • When Will Cicadas Go Away?

    Introduction

    Cicadas are fascinating insects known for their distinctive sounds and periodic mass emergences. These events, while remarkable, often lead people to wonder, “When will the cicadas go away?” This article delves into the life cycles of cicadas, their environmental and economic impacts, and the scientific predictions about their emergence and disappearance. By understanding these aspects, we can better appreciate the role of cicadas in our ecosystem and anticipate their behavior.

    Cicada Life Cycles

    Types of Cicadas

    There are two primary types of cicadas: annual cicadas and periodical cicadas. Each type has a different life cycle, which significantly affects when they appear and disappear.

    Annual Cicadas

    Annual cicadas, also known as “dog-day cicadas,” emerge every year. They typically have a 2-5 year life cycle, but their broods are staggered, so a portion of the population emerges each summer. These cicadas are known for their relatively low populations and their appearance during the hotter parts of the summer.

    Periodical Cicadas

    Periodical cicadas are unique to North America and are known for their synchronized, mass emergences every 13 or 17 years. These cicadas belong to the genus Magicicada and are divided into different broods, each with its specific emergence year. Their life cycle involves a lengthy underground development phase, followed by a short, intense above-ground adult phase.

    Life Cycle Stages

    The life cycle of cicadas consists of three main stages: egg, nymph, and adult.

    Egg Stage

    Female cicadas lay their eggs in tree branches. After a few weeks, the eggs hatch into nymphs. The timing of this stage is crucial as it sets the initial stage for the next phase of their life cycle.

    Nymph Stage

    Once hatched, the nymphs drop to the ground and burrow into the soil. Here, they will spend the majority of their lives, feeding on root sap. For annual cicadas, this stage lasts 2-5 years, while for periodical cicadas, it lasts 13 or 17 years, depending on the brood.

    Adult Stage

    The final stage is the adult phase, where cicadas emerge from the ground, molt, and become winged adults. This stage is characterized by mating and egg-laying activities, lasting only a few weeks. After mating, the adults die, and the cycle begins anew.

    The Timing of Cicada Emergence and Disappearance

    Environmental Triggers

    Cicada emergence is primarily driven by environmental factors. Soil temperature, reaching approximately 64°F (18°C) at a depth of 8 inches, is a key trigger for the emergence of periodical cicadas. This typically occurs in late spring or early summer, depending on the region.

    Brood Patterns

    Periodical cicadas are organized into broods, each emerging in specific years. For example, Brood X, one of the most famous broods, emerged in 2021. Understanding the patterns of these broods helps predict when large-scale emergences will occur.

    Climate Change Impact

    Climate change can alter the timing of cicada emergence. Warmer temperatures might cause early emergences or shift the geographic range of cicadas. Scientists are studying these effects to better predict future emergence patterns.

    The Impact of Cicada Emergence

    Environmental Impact

    Cicadas play a significant role in their ecosystems. Their emergence has both positive and negative effects on the environment.

    Positive Effects

    • Soil Aeration: When nymphs burrow and emerge, they aerate the soil, which can benefit plant roots.
    • Nutrient Cycle: The decaying bodies of adult cicadas provide a nutrient boost to the soil.
    • Food Source: Cicadas serve as a food source for various predators, including birds, mammals, and other insects.

    Negative Effects

    • Tree Damage: Egg-laying can damage young trees and shrubs, sometimes leading to branch dieback.
    • Noise Pollution: The loud, continuous mating calls of male cicadas can be disruptive to human activities.

    Economic Impact

    Cicada emergences can also have economic implications.

    Agriculture

    While cicadas generally do not pose a significant threat to crops, their egg-laying can damage young orchards and ornamental plants. Farmers and gardeners may need to take protective measures during large emergences.

    Tourism

    Cicada emergences can attract tourists and naturalists, providing a boost to local economies. Special events and merchandise related to cicada emergences can generate revenue.

    Public Perception

    Cicadas often evoke mixed reactions from the public. While some people find their mass emergences fascinating and a marvel of nature, others may find them a nuisance due to their noise and sheer numbers.

    Scientific Predictions and Research

    Tracking and Monitoring

    Scientists use various methods to track and monitor cicada populations. These methods include:

    • Field Surveys: Researchers conduct field surveys to document cicada emergence and population density.
    • Citizen Science: Public participation in tracking cicada sightings helps gather data over a wide area.
    • Technological Tools: Advances in technology, such as environmental sensors and modeling software, aid in predicting cicada emergences.

    • Genetics: Studying the genetic makeup of cicadas to understand their long life cycles and synchronized emergences.
    • Climate Impact: Investigating how climate change affects cicada emergence patterns and distribution.
    • Ecological Role: Exploring the ecological role of cicadas and their interactions with other species.

    Predicting Future Emergence

    Scientists use historical data, climate models, and field observations to predict future cicada emergences. These predictions help prepare for the environmental and economic impacts of large-scale emergences.

    Coping with Cicada Emergence

    Home and Garden Protection

    Homeowners and gardeners can take steps to protect their property during cicada emergences:

    • Netting: Use netting to protect young trees and shrubs from egg-laying damage.
    • Delay Planting: Delay planting new trees and shrubs until after the cicada emergence.
    • Pruning: Prune dead or damaged branches to reduce the impact of cicada egg-laying.

    Managing Noise

    The noise produced by cicadas can be overwhelming. Here are some strategies to manage it:

    • Soundproofing: Use soundproofing techniques in homes and offices to reduce noise.
    • Ear Protection: Wear ear protection when spending extended time outdoors in heavily infested areas.
    • Embrace the Noise: Understanding that the noise is temporary and part of a natural phenomenon can help cope with the disruption.

    Appreciating the Natural Phenomenon

    Cicada emergences are remarkable natural events that offer unique opportunities for observation and education. Embracing the phenomenon and learning about cicadas can enhance appreciation for these insects and their role in the ecosystem.

    Conclusion

    The question of “When will the cicadas go away?” is complex, involving an understanding of their life cycles, environmental triggers, and broader ecological impacts. While cicadas can be a temporary nuisance due to their noise and numbers, they play important roles in their ecosystems.
