Spotted Lanternfly Adult and Nymphs (IMAGE) Entomological Society of America Caption The spotted lanternfly (<i>Lycorma delicatula</i>), adult and nymphs shown here, arrived in Pennsylvania in 2014 and has quickly become one of the top insect pests of concern there and in neighboring states. While its preferred host is tree of heaven (<i>Ailanthus altissima</i>), the spotted lanternfly has been reported to attack more than 70 plant species, including grapes, apples, cherries, and several other fruit and timber tree species. A new habitat-modeling study shows most of New England and the mid-Atlantic states as well as parts of the central US and Pacific Northwest are vulnerable to establishment of the spotted lanternfly if it finds its way there.
