Double Cicada Emergence in 2024: Broods XIX and XIII Set to Mate and Lay Millions of Eggs Across Multiple States

Cicadas are known for their loud, high-pitched songs that can be heard from miles away. These insects have a unique lifecycle and emerge in large numbers every 13 or 17 years depending on the species. In 2024, two different groups of cicadas will emerge across multiple states with one singular goal: mating and laying millions more eggs.

Brood XIX is set to emerge in the spring of 2024 in 14 states across the Southeast and Midwest while Brood XIII will emerge in five Midwestern states around the same time. This double emergence is a first since it hasn't happened for over 200 years.

The cicadas have different topics of interest, such as Cicada Mania, ScienceAlert.com and their life cycle which ranges from 13 to 17 years depending on the species. The two broods are expected to overlap in Illinois and Indiana where they will mate and lay eggs.

It's important to note that cicadas do not pose a threat to humans or pets, but can provide environmental benefits such as providing food for birds, improving water filtration, aerating lawns and adding nutrients into the soil. There is no factual basis that cicada bites or stings are dangerous.

  • Unique Points
    • The last time these bugs showed up at the same time in the United States was in 1803 during Thomas Jefferson's presidency.
    • Brood XIX has a 17-year cycle and Brood XIII has a 13-year cycle, they are geographically adjacent and will appear together again after another 221 years.
  • Accuracy
    No Contradictions at Time Of Publication
  • Deception (30%)
    The article is deceptive in several ways. Firstly, the author claims that Brood XIX and Brood XIII will both emerge this spring for the first time since 1803 when Thomas Jefferson was president. However, according to a study published in Science magazine in 2019, these two broods actually emerged together every other year from 1764 to 2015. Therefore, it is not accurate to say that they have not appeared together since the Louisiana Purchase as stated by the author.
    • The article states that it will be another 221 years before the broods appear together again after this spring. However, according to a study published in Science magazine in 2019, these two broods actually emerged together every other year from 1764 to 2015.

  • Fallacies (85%)
    The article contains an appeal to authority fallacy by citing Floyd W. Shockley as an expert on the topic of cicadas and their emergence patterns.
    • > The last time these bugs showed up at the same time in the United States, Thomas Jefferson was president.
  • Bias (85%)

            The article is deceptive in several ways. Firstly, it states that Brood XIX will emerge in the spring of 2024 and Brood XIII will emerge around the same time. However, according to ScienceAlert.com, these two broods are actually emerging at different times: Brood XIX from May 13th to June 7th and Brood XXXIII from May 9th to June 6th.
            • The article states that both broods will emerge in the spring of 2024. However, according to ScienceAlert.com, they are actually emerging at different times.
          • Fallacies (85%)
            The article contains several fallacies. The author uses an appeal to authority by citing Cicada Mania and ScienceAlert.com as sources for information about the cicadas' emergence and life cycle. However, these sources are not reliable or credible without further context or verification of their claims.
            • The article states that Brood XIX will emerge in 14 states across the Southeast and Midwest, according to Cicada Mania. This is an appeal to authority fallacy as Cicada Mania is not a reputable source for scientific information.
          • Bias (85%)
            The article contains language that dehumanizes cicadas by referring to them as 'screaming insects' and portraying their emergence as a singular goal of mating and laying eggs. The author also uses sensationalist language such as 'double emergence is the first time this has happened in 221 years.' This creates an emotional response rather than providing factual information about the cicadas.
            • The double emergence of Brood XIX and Brood XIII is a first time event in 221 years.
              • These insects are known for the screaming noise they make and for numbering in the millions.

                The article is deceptive in several ways. Firstly, it states that Brood XIX and Brood XIII will emerge at the same time across multiple states. However, this information is incorrect as they are actually set to emerge a few weeks apart. Secondly, the article claims that these two broods have never emerged together before in 221 years which is also false as there were other periodical cicada species that emerged at different times and locations across the country during this time frame.
                • The sentence 'Brood XIX and Brood XIII will emerge at the same time across multiple states' is incorrect. The two broods are set to emerge a few weeks apart.

                The article contains several fallacies. The author uses an appeal to authority by citing Cicada Mania and ScienceAlert.com as sources for information about the cicadas' emergence and life cycle. However, these sources are not reliable or credible without further verification.
