The invasive spotted lanternfly (Lycorma delicatula) uses tree of heaven (Ailanthus altissima) as its primary host but was known to use at least 65 plants for feeding or egg deposition—though most of those were known via research in the insect’s native Asia. A new review of existing research and other observations brings the worldwide total of plants the insect will feed on to 103—of which 56 are present in North America. (Photo by Eric R.
