'Dangerously Invasive' Fly Officially Spotted In Bucks County

By Justin Heinze:

A dangerously invasive fly that has been sweeping across Pennsylvania has been officially spotted in Bucks County, according to the Pennsylvania Department of Agriculture.

The spotted lanternfly disproportionately consumes grapevines, apple trees, stone fruit trees, and pine trees and has the potential to destroy ecosystems, according to officials.

It’s serious enough that a “quarantine” has been implemented in several townships in Bucks and Montgomery counties, officials said.

The ”quarantined” locations in Bucks County include Milford Township and Trumbauersville

Montgomery County locations affected include Upper Hanover, Red Hill, Pennsburg, and East Greenville. In Chester County, only South Coventry Township has been affected.

Under the quarantine, any business that stores products outside must first be approved by an inspector from the state department of agriculture.

That includes not just firewood and organic material, but companies that showcase items on patios or sidewalks or parking lots, like hardware stores, supermarkets, and car dealers.

Over the summer, the lanternfly was spotted throughout the state, including in Berks county. The first discovery of the bug, also known as Lycorma delicatula, was made in the fall of 2014 in Berks County.

Since then, more than 100,00 spotted lanternflies have been killed.

“Pennsylvania is a leader in the country for timber production and we have quite a large grape industry and we have orchards, so it definitely has been introduced to a sensitive area,” Emelie Swackhamer, Penn State Extension Educator, told 6 ABC.

Nymph and adult spotted lanternflies cause extensive damage when they feed, sucking sap from stems and leaves and causing the plant to ooze and weep.

Not only does the plant die but the “fermented odor” caused by the feeding, along with the fluid excreted by the insects themselves, promotes mold growth and draws even more insects, according to the U.S. Department of Agriculture.

The lanternfly is a native to the Asian countries of China, Indian, Japan, and Vietnam.

It has done invasive damage to Korea, where officials say it has attacked 25 plant species that also grow in Pennsylvania.

The state released the following tips to residents:

• If you see eggs: Scrape them off the tree or smooth surface, double bag them, and throw them in the garbage or place the eggs in alcohol or hand sanitizer to kill them.
• If you collect a specimen: Turn the adult specimen or egg mass in to the department’s Entomology Lab for verification. First, place the sample in alcohol or hand sanitizer in a leak proof container.
• If you take a photo: Submit photo of adults or egg masses to badbug@pa.gov.
• If you report a site: Call the Bad Bug hotline at 1-866-253-7189 with details of the siting and your contact information.
