Study sites. Map of Hokkaido (a) showing the moth-abundant sites along the expressways managed by E-NEXCO (blue) overlaid on cool-temperate region (magenta) and subarctic region (green) layers. Mountain areas are shown in dark green. Field experiments in 2014 and 2015 were conducted in the back area of the Mt. Usu (Usuzan) rest area (a, b) and those in 2017 and 2018 were conducted on a hill on flat ground beneath an elevated expressway close to the Yubari Interchange (a, c). Both study sites had few commercial lights and were surrounded by forests (b, c). Scale bars = 100 km in a; 200 m in b and c
