Spotted lanternfly adult and nymph (IMAGE) Entomological Society of America Caption The spotted lanternfly (Lycorma delicatula) is a treehopper native to Asia but was discovered in Pennsylvania in 2014, and it has since spread to five other northeastern states. Its primary host is tree of heaven (Ailanthus altissima), but it is known to feed on more than 100 types of plants--mostly trees, shrubs, and stout vines. Valuable crops the spotted lanternfly can damage include grapes, apples, and peaches, as well as hardwood trees. One study of the lanternfly's potential range in the U.S., based on environmental and climatic conditions, suggests most of New England and the mid-Atlantic states as well as parts of the central U.S. and Pacific Northwest are vulnerable to establishment of the spotted lanternfly if it finds its way there. A new collection curated by the Entomological Society of America's family of journals showcases the growing body of research that is helping us understand the spotted lanternfly's biology and how to contain it.
