The annoying, now-annual hatching of spotted lanternflies is less than a month away, and experts warn there could be millions across New York City<\/a> this year.<\/p>\n

According to New York\u2019s Department of Agriculture, this past winter<\/a> wasn\u2019t cold enough to reduce the insect\u2019s population. As a result, officials expect the species to surge again this season.<\/p>\n

“Predicting the spotted lanternfly population for the coming season is extremely difficult, as the research community continues to work on pinpointing what factors influence the population from year to year,” Jola Szubielzki, director of public information at the Department of Agriculture, said. “We do know that winter temperatures<\/a> downstate were not cold enough for long enough to kill off eggs that overwintered.”<\/p>\n

The insect, that looks like a cross between a moth and a ladybug, is native to Asia<\/a> and was first discovered in the U.S. in Pennsylvania<\/a> in 2014.<\/p>\n

Now, the lanternfly has been spotted in more than 21 states, including New York<\/a>, New Jersey<\/a>, Connecticut<\/a>, Virginia<\/a> and Ohio<\/a>, and has become a persistent nuisance in New York City each summer<\/a> since 2020.<\/p>\n

“Cities tend to have milder winters, creating favorable conditions for species that otherwise would only be able to live in warmer climates,” Kristen Winchell, an assistant professor of biology at New York University, said in a press release.<\/p>\n

Officials say these bugs will continue to spread, especially as they continue to hitchhike by laying egg masses on vehicles, trains, shipping materials and outdoor<\/a> surfaces, according to the Virginia Department of Agriculture.<\/p>\n

“Cities are also highly connected places where trade happens, and organisms may end up on shipments in planes or boats traveling between cities,” Winchell said. “Finally, urban environments aren\u2019t very friendly to a lot of native species, so you have a degraded ecological community that creates opportunities for new species to come in.”<\/p>\n

Each year, female lanternflies<\/a> typically lay one or two egg masses, each containing about 30 to 60 eggs. They cover them with a creamy, mud-like substance that acts as camouflage to protect the egg sacs, according to Cornell University.<\/p>\n

The eggs are laid in the fall and hatch in the spring<\/a>, with young nymphs emerging as early as May and maturing into adults later in the summer<\/a>.<\/p>\n

In a 2024 study from New York University, researchers found that the bugs are living up to five months longer than they did when they first arrived, due to the climate<\/a> of urban environments.<\/p>\n

“This is important because a lengthening of the active period each year means they have more time to reproduce and spread,” Winchell said.<\/p>\n

While lanternflies<\/a> don\u2019t bite or sting and aren\u2019t directly harmful to humans or pets, they do pose a serious threat to agriculture.<\/p>\n

The insects feed by sucking sap from plants, weakening trees and crops like grapes, apples and hops. They also leave behind a sticky substance known as honeydew, which promotes the growth of mold.<\/p>\n

Officials warn that the economic impact of these invasive species could be significant.<\/p>\n

Residents are encouraged to take immediate steps to help contain the spread, including using pesticides, removing egg masses and participating in the stomp-it campaigns.<\/p>\n

“Vigilance and proactive control methods, such as egg mass scraping, are still needed, even during the early spring months,” Szubielzki said.<\/p>\n
