The spotted lanternfly (Lycorma delicatula) was first identified in Indiana in July 2021 in Switzerland County. Since then, populations have spreading rapidly across the state (Figure 1). This is the time of the year that the insects are in their most recognizable adult state (Figure 2). Early detection is crucial to stop the spread.
