Spotted Lanternfly Technical Report

A Technical Report from The Bartlett Tree Research Laboratories

Spotted lanternfly (SLF), Lycorma delicatula, is an invasive planthopper that was first discovered in the U.S. in Berks County, PA in 2014.  Despite signficant, large-scale management efforts, this insect has continued to spread across the East Coast and into the Midwest. Spotted lanternfly’s native range is thought to be throughout most of China but it has also invaded nearby countries such as South Korea, where it has become a major pest of grapes and peaches. In the U.S., SLF has proven to be a signficant economic and nuisance pest.
