Invasive spotted lanternfly may not damage hardwood trees as previously thought

In 2012, when the spotted lanternfly (Lycorma delicatula) arrived in the U.S. from its home in China, scientists, land managers, and growers were understandably concerned that the sap-feeding insect would damage native and commercial trees. New long-term research led by Penn State has discovered that hardwood trees, such as maple, willow and birch, may be less vulnerable than initially thought.
