Spotted Lanternfly Update

 Winter is a good time to scout for spotted lanternfly (SLF) egg masses on trees, outdoor furniture, and vehicles. Inspect tree trunks, the under sides of branches, and horizontal surfaces near the ground. It is especially important to check vehicles that have traveled into or through infested areas last summer and fall. Look in the wheel wells, behind spare tires, and in all the nooks and crannies where an insect can hide an egg mass. 

Egg masses are a gray-brown color and about 1.5 inches in length. The female lays approximately 40-60 eggs, then covers them with a putty-like substance. As this covering ages, it gets lighter and cracks.

SLF was first found in Pennsylvania in 2014 and has since spread throughout several eastern states. In 2021, small populations were also confirmed in Ohio and Indiana. As with any exotic invasive pest, early detection is key to effective control.  No SLF has been found in Nebraska to date. 

If you think you’ve found an SLF egg mass, take pictures or collect a specimen, and report your suspicions to your NDA Entomology Inspector, or contact Julie Van Meter, NDA Entomology Program Manager/State Entomologist at 402-471-6847 or Julie.vanmeter@nebraska.gov .
