Spotted Lanternfly inAurora, ILSPOTTED LANTERNFLY GUIDE
Aurora — Illinois's second-largest city and a major western suburb of Chicago — entered the SLF watch zone in 2024 as spotted lanternfly advanced into the Chicago metro region. DuPage and Kane Counties' position along the Fox River and Metra rail network create multiple introduction and dispersal pathways from the east. The former industrial corridor along the Fox River has significant Tree of Heaven colonization that warrants active monitoring as SLF pressure builds in northeastern Illinois.

Tree of Heaven in Aurora, IL
Fox River banks through Aurora and the Fox Valley corridor have Tree of Heaven populations in disturbed riparian habitat that provide prime SLF establishment zones running north-south through the western suburbs. The Metra rail corridor connecting Aurora to downtown Chicago is a freight and commuter pathway with rail-margin ToH that represents a key SLF spread vector. Former industrial sites throughout Aurora's historic manufacturing districts have heavy Tree of Heaven colonization in brownfield habitat that is an early-detection priority for Kane and DuPage Counties.
