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…]

A natural wonder will occur in 15 states this year: the emergence of the Brood X, 17-year periodical cicadas! Also known as “17-year or 13-year locusts” the last mass emergence of these insects occurred in 2004. Now, 17 years later, the immature cicadas will emerge from the ground, molt one last time to gain wings,[Read More…]
