Description: The spotted lanternfly is native to China, India, and Vietnam. Since the first detection in Berks Co., PA in 2014, populations have spread to several surrounding counties in Pennsylvania, as well as Virginia, New Jersey, Delaware, Maryland, West Virginia, New York, Connecticut, and most recently Ohio. Additionally, interceptions have occurred in Massachusetts, New Hampshire, Maine, and Oregon where a single spotted lanternfly was sighted, but no infestation was found.
Nymphs and adults have been reported to feed on 70+ host plant species. Spotted lanternflies are planthoppers in the family Fulgoridae, which have piercing-sucking mouthparts that are used to feed on the phloem of their hosts. Their broad host range includes grapevines, fruit trees, ornamentals, hardwoods and more. However, current research and field observations have demonstrated a preference for certain hosts, such as tree-of-heaven (Ailanthus altissima), grapevines, black walnut, hops, and maples. For a full list of known hosts, see the SLF North American Plant Usage list.
Host plant preferences may vary based on spotted lanternfly life stage, time of year, availability of hosts in the landscape, and health of trees. Understanding seasonal host phenology of the spotted lanternfly will aid in effective management of this pest. This information came from: https://web.uri.edu/biocontrol/spotted-lanternfly.
