The increasingly dreaded lanternfly season has arrived, and officials are warning Americans to be vigilant in order to avoid the pesky spotted pests this summer. The US Department of Agriculture (USDA) is advising the public to specifically look out for spotted lanternfly eggs and to promptly destroy them upon detection. It is crucial to detect and destroy the eggs early on, as hatching season occurs between May and June, providing an opportunity to eliminate the eggs before they can cause significant damage to crops and plants. The USDA emphasizes the importance of killing any brown-colored spotted lanternfly eggs found on vehicles, trailers, outdoor equipment, or patio furniture to prevent the insects from spreading and causing harm.
The spotted lanternflies, originally from southeast Asia, have wreaked havoc on crops and plants in Pennsylvania, resulting in $550 million in damages in 2019, according to Nature. These insects are known to be destructive once their eggs hatch, feeding on crops such as apples and grapes, as well as hardwood trees. The USDA warns that the spotted lanternflies are “swarm feeders” of grapes, posing a serious threat to farmers. Their feeding habits can weaken vines, leading to various issues such as loss of winter hardiness, reduced crop yield, or even vine death. It is essential for individuals to inspect vehicles, belongings, and outdoor items for lanternfly egg masses, nymphs, and adults, and eliminate these life stages to prevent the spread of the pests.
In addition to causing damage through feeding, spotted lanternflies leave behind a sticky residue called honeydew, which attracts other insects and can promote the growth of sooty mold, further harming plants. The presence of spotted lanternflies in an area can also have a significant impact on the environment and agriculture. A study from Cornell University College of Agriculture and Life Sciences reported up to 400 adult spotted lanternflies per vine on grape plants, indicating the extent of the infestation and the potential consequences for vine health and crop yield. The destructive nature of the spotted lanternfly has been observed in various regions, with New York also being identified as a new hotspot for the invasive species.
During the summer of 2022, the presence of spotted lanternflies in New York City caused concerns among residents, as the insects were seen jumping and flying around. The USDA has identified New York as one of 16 states where the spotted lanternfly has become a significant problem since its initial detection in Pennsylvania in 2014. To combat the spread of the invasive species and protect crops and plants, individuals are urged to be proactive in inspecting and eliminating spotted lanternfly eggs and insects in their surroundings. By taking these preventative measures and staying informed about the threats posed by the spotted lanternfly, Americans can help mitigate the impact of these destructive pests and safeguard agricultural resources.
