HOLYOKE, Mass. (WWLP) – The Massachusetts Department of Agricultural Resources is alerting Holyoke residents of the discovery of an invasive species found in the city, the Spotted Lanternfly.

The department says an infestation of Spotted Lanternfly was recently confirmed in Holyoke. It is not clear how this invasive species made its way to Holyoke but the insect is known to have been spotted previously in Springfield, Worcester and parts of Connecticut.

This pest feeds on sap and can damage or kill over 100 types of plants including grapevines, fruit trees, maples, hops, and blueberries. Additionally, they swarm during mating season causing an impact on outdoor activities.

Bob Russell, Entomologist at American Pest Solutions, tells 22News, “They are native to China and were first detected in the East Coast. Check your outdoor furniture, scrape any egg masses off and dispose of them. Inspect any trees on your property for signs of the pest. Especially at dusk they tend to gather in large groups on the trunks of trees.”

Where you can spot a Spotted Lanternfly

The bug can be found congregating on sides of buildings, in or on vehicles, or on plants they prefer to attack, including tree of heaven, grape and walnut.

What to do if you find a Spotted Lanternfly egg mass

If you happen to come across an egg mass of the Spotted Lanternfly, MDAR encourages you to take a photo and report it to the department online or by emailing slf@mass.gov. An egg mass is typically gray or beige in color, about an inch and a half long and can be found on any flat surface. They are typically found on tree bark, fenceposts, other wood products and rusty metal.
