Spotted lanternfly on tree limb.Spotted lanternfly is a major pest of concern across most of the United States. Spotted lanternfly (SLF) is an invasive planthopper native to China that was first detected in the United States in Pennsylvania in 2014. SLF feeds on over 70+ plant species including fruit, ornamental and woody trees with tree-of-heaven as its preferred host. Spotted lanternfly is a hitchhiker and can easily be moved long distances through human assisted movement.

Tree of heaven (TOH) is the preferred host for the spotted lanternfly (SLF).  The ability to identify TOH will be critical to monitoring the spread of this invasive pest as the 4th-stage nymphs and adult spotted lantern-flies show a strong preference for TOH.
