ID Aids for the spotted lanternfly

In February of this year, USDA approved $17.5 million in emergency funding to help Pennsylvania combat the spotted lanternfly (Lycorma delicatula). Plant protection officials warn this invasive pest can cause substantial economic damage, as it feeds on a wide variety of host plants and crops, including almonds, apples, grapes, hops, stone fruits, and walnut trees. They may congregate on their hosts to feed in great numbers, thereby draining a host's nutrients. Their honeydew waste product also causes sooty mold to grow, further contributing to host decline.

Despite its name, this pest is a planthopper in the order Hemiptera. Native to Asia, the spotted lanternfly has quickly spread since its initial detection in 2014. The insect is not a strong flier, yet its U.S. range is expanding, mostly due to the movement of vehicles, outdoor furniture, or other objects to which females glue their inconspicuous egg masses.

We selected this set of ID Aids to help identify the spotted lanternfly in all its life stages, from egg mass through adult.
