How Much Longer Will The Cicadas Be Here this year? The emergence of Brood XIX and Brood XIII cicadas has sparked curiosity and perhaps a bit of concern. At HOW.EDU.VN, we provide expert insights into understanding the cicada life cycle and predicting their duration above ground, connecting you with leading entomologists for personalized guidance. Learn about cicada emergence, cicada broods, and insect life cycles to prepare yourself for their departure.
1. Understanding the 2024 Cicada Emergence
Cicadas, particularly the periodical cicadas of Broods XIX and XIII, have captured public attention due to their synchronized emergence. This phenomenon occurs when the soil temperature at a depth of 8 inches reaches 64 degrees Fahrenheit, often triggered by a warm rain, according to Cicada Mania. The early warmth in many states has already led to sightings across the Southeast and Midwest.
1.1. Factors Influencing Emergence Timing
The timing of cicada emergence is influenced by several environmental factors:
- Soil Temperature: The critical threshold of 64 degrees Fahrenheit at an 8-inch depth.
- Rainfall: Warm rain events often trigger mass emergences.
- Geographic Location: Southern states tend to see earlier emergences due to warmer climates.
1.2. Impact of Climate Change
Climate change and the shifting weather patterns is making this natural phenomenon more erratic. The changing climate may cause shifts in emergence timing, potentially leading to earlier or more prolonged cicada seasons. Scientists at HOW.EDU.VN are closely monitoring these changes to provide accurate predictions.
2. Life Cycle of Periodical Cicadas
Understanding the life cycle of periodical cicadas is crucial for predicting how long they will remain above ground. These cicadas have either a 13-year (Brood XIX) or a 17-year (Brood XIII) life cycle.
2.1. Underground Development
Cicada nymphs spend the majority of their lives underground, feeding on tree roots. This subterranean phase lasts either 13 or 17 years, depending on the brood.
2.2. Emergence and Mating
Once they emerge, adult cicadas focus on mating. Male cicadas produce loud calls to attract females. After mating, females lay eggs in tree branches.
2.3. Post-Mating Lifespan
After mating and laying eggs, adult cicadas typically live only a few weeks above ground. This post-mating lifespan is generally between three to six weeks.

3. Predicting Cicada Die-Off
Predicting when cicadas will die off involves considering their emergence timing and typical lifespan as adults. Most cicadas from Broods XIX and XIII are expected to die off in June, though some may persist into late May or July, depending on their individual emergence times.
3.1. Peak Emergence and Lifespan
Cicadas typically emerge over several weeks, with a peak period followed by a gradual decline. Their adult lifespan ranges from three to six weeks, influencing when they begin to die off.
3.2. Regional Variations
The die-off period can vary regionally due to differences in local climate and soil temperatures. Areas with earlier emergences will likely see earlier die-offs.
3.3. Factors Affecting Cicada Lifespan
Several factors can affect a cicada’s lifespan:
- Weather Conditions: Extreme weather can shorten or extend their lifespan.
- Predation: Predators can reduce the number of cicadas in an area.
- Habitat Quality: Access to suitable mating and egg-laying sites influences survival rates.
4. Geographic Distribution of Broods XIX and XIII
Broods XIX and XIII have distinct geographic distributions, with some overlap in certain areas. Understanding these distributions helps in predicting regional die-off patterns.
4.1. Brood XIX: The 13-Year Cicadas
Brood XIX is primarily located in the Southeast, including states such as Georgia, South Carolina, and North Carolina.
4.2. Brood XIII: The 17-Year Cicadas
Brood XIII is mainly found in the Midwest, including states such as Illinois, Indiana, and Wisconsin.
4.3. Overlap Zones
Illinois and Iowa are two states where the ranges of Broods XIX and XIII overlap, leading to significant cicada activity.
5. Monitoring and Tracking Cicada Activity
Monitoring and tracking cicada activity can provide valuable insights into their emergence and die-off patterns. Citizen science initiatives and professional entomological surveys play a crucial role in this effort.
5.1. Citizen Science Projects
Citizen science projects encourage the public to report cicada sightings, helping to map their distribution and track emergence times.
5.2. Entomological Surveys
Entomologists conduct systematic surveys to monitor cicada populations and gather data on their life cycle and behavior.
5.3. Data Analysis and Modeling
Collected data is analyzed to create predictive models that forecast cicada die-off times based on factors such as temperature, rainfall, and geographic location.
6. Impact of Cicada Emergence on the Environment
Cicada emergence has significant impacts on the environment, both positive and negative. Understanding these impacts helps in managing ecosystems during cicada seasons.
6.1. Effects on Vegetation
Female cicadas lay eggs in tree branches, which can cause damage to young trees. Mature trees usually withstand this damage, but young trees may require protection.
6.2. Benefits to Soil and Wildlife
Cicada emergence aerates the soil as nymphs burrow out, and the decaying bodies of adult cicadas provide nutrients to the soil. Additionally, cicadas serve as a food source for birds and other wildlife.
6.3. Ecosystem Dynamics
The mass emergence of cicadas can disrupt predator-prey relationships, as predators focus on cicadas as an abundant food source.
7. Managing Cicada-Related Concerns
While cicadas are not harmful, their emergence can be a nuisance for some people. Here are some strategies for managing cicada-related concerns.
7.1. Protecting Young Trees
Wrapping young trees with netting can prevent cicadas from laying eggs in their branches, protecting them from damage.
7.2. Reducing Noise
While it’s difficult to eliminate cicada noise, reducing outdoor activities during peak emergence times can help minimize disturbance.
7.3. Chemical Controls
Insecticides are generally not recommended for cicada control, as they can harm beneficial insects and have limited effectiveness.
8. Debunking Common Myths About Cicadas
Several myths surround cicadas, and it’s important to debunk these to understand their behavior and impact accurately.
8.1. Myth: Cicadas are Locusts
Cicadas are often mistaken for locusts, but they are distinct insects with different life cycles and behaviors.
8.2. Myth: Cicadas Bite or Sting
Cicadas do not bite or sting. They are harmless to humans and do not pose a threat.
8.3. Myth: Cicadas Destroy Crops
While cicadas can damage young trees, they do not typically destroy crops. Their primary impact is on woody vegetation.
9. The Cultural Significance of Cicadas
Cicadas have cultural significance in various societies, often appearing in art, literature, and folklore.
9.1. Cicadas in Art and Literature
Cicadas have been depicted in art and literature for centuries, often symbolizing transformation and rebirth.
