The Spotted Lanternfly found in Arlington on 10-3, was dead and was found by a resident, who happens to be a Master Naturalist volunteer in Arlington. It came with packaging on produce purchased from a local grocery store that originated in an area (Pennsylvania) where the bugs are well established.
We are on high alert for sightings of this invasive pest. This pest which feeds on a wide variety of plants is a leafhopper that uses piercing sucking mouthparts to do damage to stems and branches. Populations build rapidly once established and it is a pest of significant economic concern for grapes and fruit trees. It has a large array of host plants including it’s preferred host, the invasive non-native Ailanthus altissima https://www.fs.fed.us/database/feis/plants/tree/ailalt/all.html
Other concerns requiring public education include the production of large amounts of excrement that produces heavy growths of sooty mold on the plant and on the ground below where it is feeding and the use of systemic and broad spectrum insecticides that will threaten beneficial insects. Thank you all for your help in getting the word out.
