Landscapes and vegetation are critical factors in dispersion of exotic insects and expansion of their range. However, few studies have addressed how the surrounding landscape affects the establishment of exotic insects. We assessed the relationship between establishment of an exotic lace bug Corythucha marmorata (Uhler) and the surrounding landscape in the northern edge of the lace bug's expanded range. We found that the lace bugs showed variability in their density among populations. Urban areas had a positive effect, while the natural forest vegetation had a negative effect on lace bug density, with a buffer range of 1–2 km. Moreover, their abundance decreased with distance from the source population. Our results suggest that natural forest landscapes in urban areas may inhibit the range expansion of invasive insects that feed on exotic plants growing in human‐disturbed habitats.
