Pennsylvania Cicadas 2024: Will They Invade Your Backyard?

The anticipated emergence of periodical cicadas in Pennsylvania has generated considerable buzz, especially surrounding the phenomenon of Brood XIX. Entomologists from institutions like Penn State University are closely monitoring the situation. The lifecycle of these insects, a topic extensively covered by organizations like the Pennsylvania Department of Conservation and Natural Resources (DCNR), influences their emergence patterns. For residents across the state, understanding these patterns is crucial to preparing for the inevitable arrival of the 2024 cicadas pennsylvania.

Pennsylvania Cicadas 2024: Will They Invade Your Backyard?

This article aims to provide residents of Pennsylvania with a clear understanding of the 2024 cicada emergence, particularly concerning the potential impact on their backyards. We will explore which areas are most likely to be affected, what to expect during the emergence, and how to manage cicada activity.

Understanding the 2024 Cicada Emergence

The year 2024 marks a significant cicada event because two broods are emerging simultaneously: Brood XIII and Brood XIX. While Brood XIII is specific to the Midwest, Brood XIX, the Great Southern Brood, will be of interest to some Pennsylvania residents. This rare overlapping emergence hasn't occurred in over 200 years, making accurate information crucial.

Brood XIX and Pennsylvania

Brood XIX is a 13-year periodical cicada brood. However, its impact on Pennsylvania is not expected to be widespread. Unlike some other states, large portions of Pennsylvania will not experience a significant emergence of Brood XIX.

• Limited Geographic Reach: The areas most likely to see Brood XIX activity are in the far southwestern corner of the state. This is crucial for readers to understand upfront – most of the state will not be heavily impacted.
• Focus on Specific Counties: Instead of saying "Pennsylvania," narrow the focus to counties such as Greene County or Fayette County. Provide a map if possible.
• Lower Density Compared to Other Broods: Even in affected areas, the density of cicadas may be lower compared to historical emergences of local 17-year broods.

Why the Focus on "2024 Cicadas Pennsylvania"?

The reason for the heightened interest is the combination of Brood XIX’s emergence with the general public awareness campaigns regarding periodical cicadas. Many Pennsylvanians are naturally curious about whether these insects will affect them. This article addresses this specific concern.

Identifying Cicadas: What to Look For

Accurate identification is essential. Knowing the difference between periodical cicadas and annual cicadas helps alleviate unnecessary concerns.

• Periodical Cicadas (Brood XIX):
  • Color: Dark body with reddish-orange eyes and wing veins.
  • Size: About 1 to 1.5 inches long.
  • Emergence Pattern: Appear in mass emergences every 13 years (Brood XIX) or 17 years.
• Annual Cicadas:
  • Color: Greenish or brown.
  • Size: Similar to periodical cicadas.
  • Emergence Pattern: Emerge every year in smaller numbers.

Key Differences Summarized

The Cicada Life Cycle and Its Impact

Understanding the cicada life cycle helps explain why they emerge in such large numbers and the potential impact on vegetation.

1. Nymph Stage: Cicadas spend most of their lives underground as nymphs, feeding on tree roots. Brood XIX nymphs have been underground for 13 years.
2. Emergence: When soil temperatures reach a certain threshold (around 64°F), the nymphs emerge from the ground.
3. Mating: Male cicadas create a loud buzzing sound to attract females.
4. Egg Laying: After mating, females lay eggs in tree branches.
5. Hatching: The eggs hatch, and the new nymphs drop to the ground to begin the cycle anew.

Potential Impact on Trees

• Egg-Laying Damage: The egg-laying process can sometimes cause damage to young trees. This is because the female cicada makes slits in the branches.
• Branch "Flagging": This damage can cause small branches to die and turn brown, a phenomenon known as "flagging."
• Older Trees Usually Unaffected: Mature trees are generally not significantly harmed by cicada egg-laying.

Protecting Your Backyard from Cicadas (If Needed)

Given the limited impact of Brood XIX in Pennsylvania, protective measures will be relevant only to those in the far southwestern counties.

• Netting Young Trees: If you have young trees, covering them with netting can prevent cicadas from laying eggs on their branches. This is the most effective method.
• Avoid Pesticides: Insecticides are generally not recommended for cicada control, as they can harm beneficial insects and are often ineffective against the large numbers of cicadas.
• Wait and See Approach: For most Pennsylvanians, the best approach is simply to observe and enjoy the unique natural phenomenon, if any cicadas are observed.
