Last month, a highly invasive insect was spotted for the first time on the University of Michigan-Dearborn’s campus. The Environmental Interpretive Center (EIC) identified the spotted lanternfly, a sap-sucker that has been making its way across the U.S. since 2014. 

The first confirmed colony in Michigan was found in Oakland County in 2022. 

Program and natural areas manager for the EIC Rick Simek says that spotted lanternflies don’t usually kill their host trees outright, but as their numbers grow, so does the damage they can do to the environment as they feed.

Environmental harm

Infestation weakens the host tree’s ability to withstand disease, drought, and other pests.

“They have been known to kill off the saplings of a couple of native tree species,” says Simek. He lists black walnuts and maples as examples. 

Simek said that the Spotted Lanternfly’s dietary habits are especially hard on fruit-bearing plants, like the river grapes that provide nutrition for birds in the EIC’s natural area. 

The spread of the spotted lantern fly poses trouble for Michigan’s produce. “Lanternfly infestations can cause real harm to grapes, both cultivated and wild… [which is] cause for  serious agricultural and economic concern.”

Thankfully, the spotted lanternflies do not bite or pose direct harm to humans. However, the sugary “honeydew” that they excrete attracts mold, wasps, and other pests. 

Squish and scrape

What should you do once you identify a spotted lanternfly?

“One of the control methods— I’ve seen actual videos on this, it’s fairly commonly practiced—is to squish them!” says Simek. “Just make sure to become familiar with what lanternflies look like before squishing, but they are easy to identify.”

Also, remove their egg masses, which look a bit like chewed gray-brown gum, advises Simek. And it’s good to check for hitch-hiking lanternflies while entering and exiting natural areas. 

Fall is the season to look for and remove egg masses before they hatch in spring. 

Vigilance helps slow the spread

It’s important to reduce the spotted lanternfly’s ability to reproduce and spread as much as possible. 

“One of the things we don’t want to see here on campus, of course, is for it to become a breeding area that produces lanternflies that can spread around the area even more,” says Simek. Thankfully, the EIC is well maintained and better prepared for invasive visitors.

The spotted lanternfly’s preferred host, tree of heaven, has been regularly removed from the Environmental Interpretive Center’s grounds for years. Tree of heaven is a particularly entrenched invasive plant that comes from the same region as the spotted lanternfly. As a favorite food source, it is a marker of where to look for the insect. 

Additionally, birds and bats are beginning to recognize spotted lanternflies as a food source. The near 121 acres of the EIC’s natural center helps support those populations. Though, Simek notes, its being theorized that spotted lanternflies become less appetizing after eating tree of heaven. 

That’s one more reason to be diligent about removing the invasive plant. 

Report sightings

The spotted lanternfly’s impact on the tree canopy at large remains to be seen. 

The DNR says all sightings by the public should be reported. 

So far, spotted Lanternflies have been seen in Wayne, Oakland, Lenawee, and Macomb counties.

“It’s the new invasive kid on the block,” says Simek. “We’re probably going to see them more and more, and then we’re all going to find out what their impacts are.”

Michigan’s Iranian American community is concerned about the recent escalation of hostilities with Iran. 

The U.S. bombed several sites in Iran on Sunday, joining Israel’s war aimed at destroying the country’s nuclear program. 

Camron Michael Amin, a professor of Middle East and Iranian diaspora studies at University of Michigan-Dearborn, says some people were not able to get in touch with their loved ones due to an internet outage in Iran. 

“Communication seems to have improved over the course of the week, but many people couldn’t reach anybody starting sort of a week ago,” he said. “Sunday, it was hard to reach people, and that seems to have been largely driven by internet outages.”

Amin says many Iranian Americans are nervous about any escalations in the war, especially those with loved ones in Iran.

“I can’t speak for everybody, obviously, but generally speaking, Iranian Americans are nervous about and wary of anything that escalates and prolongs the war. However they feel about the Iranian government, however they feel about the issues between Iran and the United States… because they have people they know or people they care about in Iran that might be at risk they themselves visit when they can,” he said.

Amin says recent polling shows that Iranian Americans frequently keep in contact and travel to Iran as tourists or to visit family.

“So anything that makes that more dangerous or more fraught is unwelcome,” he said.

Amin says one concern is getting dual-national Iranian Americans out of Iran during the conflict.

“Certainly, dual nationals in Israel, from several countries, including the U.S., have ways to get out of that country during the fighting. And I think there’s a similar concern about dual nationals, who are Iranian Americans, who might be stuck in harm’s way during the fighting right now,” he said. 

Amin says Iranian Americans are looking to policymakers and legislators to prioritize helping people stuck in Iran.

President Donald Trump announced Monday that a ceasefire had been reached between Iran and Israel, after the deal initially faltered.
