It was only a matter of time before the highly invasive spotted lanternfly (Lycorma delicatula) made its way to western Pennsylvania but it’s disturbing to learn that it’s so close to Pittsburgh.
On 20 January 2020 the Columbus Dispatch reported that spotted lanternfly egg masses were found at the Norfolk Southern railyard in Conway, PA. They probably arrived by train and are now less than 20 miles from Downtown Pittsburgh and even closer to Ohio.
At this time of year the adult bugs are not active so an egg mass, pictured below, is the only thing they found. The authorities scraped away the egg masses and killed the eggs.
This is bad news anyway. USDA says that spotted lanternflies are the worst invasive species we’ve seen in the United States for 150 years.
