As of March 2022, Indiana has one known county with a confirmed Spotted Lanternfly (SLF) population: Switzerland County (Figure 1). Penn State University has created a SLF egg hatch prediction map that estimates the emergence of the first SLF instar based on temperature conditions (Figure 2). Please note: this map does not show where SLF[Read More…]
