What is Spotted Lanternfly?
Spotted Lanternfly, Lycorma delicatula, is an invasive insect native to Asia. Spotted Lanternfly (SLF) was originally found in the United States in Pennsylvania and was believed to be introduced and spread initially through the plant trade. It is now found in at least 19 states and feeds mainly on an invasive tree species, Tree-of-Heaven, Ailanthus altissima. Although SLF prefers Tree-of-Heaven, it has also been found to feed on black walnut, willow, and maples in different stages of the lanternfly’s lifecycle. The chart below can be helpful to determine what plants SLF can be found on throughout their lifecycle.

What is the Harm to Local Ecosystems and the Economy?
In areas with high SLF infestations, trees can suffer from major carbohydrate loss compromising health and growth. SLF feeding can also cause reduced photosynthesis and nutrient levels making trees more susceptible to other diseases and drought (Penn State Extension). Additionally, SLF infestations cause tree wilting and a moldy understory due to their secretion of sticky, sweet honeydew when feeding on sap from trees. Many industries in Indiana like forestry, logging, and wineries are likely to be the most affected by SLF spread. Economists from the Penn State College of Agricultural Sciences estimate that the current economic loss due to SLF is around $50 million within Pennsylvania with major impacts on forestry and wineries (Penn State University).
How Do I Prevent Spotted Lanternfly?
Check these places for common egg mass locations:
- Outdoor light bulbs
- Outdoor furniture
- Fence posts
- vehicle underbody, tires, and wheel wells
- camping equipment
Do regular checks in wintertime for egg masses! If you see an egg mass report it to INDNR and destroy them!
To Destroy Egg Masses:
- Scrape mass into a plastic bag
- Fill the bag with hand sanitizer or rubbing alcohol
- Zip the bag closed and throw it in the trash
