Spotted Lanternfly

The first reported identification of Lanternfly in Sullivan County, NY came from a call to our CCE Sullivan helpline. 

A Spotted Lanternfly was found dead in a yard of a Jeffersonville home owner. That same week, one was reported just outside of Port Jervis. Looking at the map below, you will see just how close we are to counties that are either under quarantine or where the presence of Spotted Lanternfly has been confirmed. It is not surprising that we have now had a confirmed siting in Sullivan and Orange counties.


Confirmed Spotted Lanternfly Locations

The spotted lanternfly, also known as Chinese blistering cicada, is a planthopper native to China and Southeastern Asia. Discovered in Pennsylvania in 2014, the spotted lanternfly presents a threat to both woody and non-woody hosts that are present throughout the United States. While their list of hosts is large, the greatest agricultural concern falls on grapes, hops, apples, blueberries, and stone fruits.

Spotted lanternfly eggs are laid on any hard, smooth surface, including plants, trunks, stones, and bricks. Because of this, egg masses may be spread unknowingly. Spotted lanternfly nymphs are able to feed on many hosts, while adults prefer Tree of Heaven (Ailanthus altissima) and grapevine (Vitis vinifera). Furthermore, abundant excretion of sticky honeydew by swarms feeding on shade trees and the associated growth of sooty mold can severely restrict people’s enjoyment of parks and their own backyards.

There is one generation per year, with adults developing in July, laying eggs in September, and overwintering as eggs. Each egg mass contains 30-50 eggs that are covered in a waxy brown substance.

The first nymphs to develop are wingless, black, and have white spots:

The final nymph stage of the spotted lanternfly is distinctively red and black:

Adults and nymphs commonly gather in large numbers on host plants to feed, and are easiest to see at dusk or at night.

This plant hopper is able to feed using specialized mouth parts that can pierce the plant and suck up sap. Both nymphs and adults feed this way, on leaves, stems, and trunks. Piercing the plant’s tissues and feeding on the sap weakens the plant, causing it to ooze and weep, which may result in a fermenting odor and a gray/black trail on the bark. Spotted lanternflies also excrete honeydew while feeding, which overtime may encourage the growth of sooty mold if infestation levels are high. The presence of the fermenting odor and honeydew may also attract other insects.
