Using MaxEnt algorithms, this study provides the first assessment of the potential distribution range of Rosalia coelestis Semenov, 1911, a longhorn beetle with a narrow trophic specialization in Northeast Asia. According to the modeling results, the current area of the most suitable habitats for the species is estimated at 3,554,100 km². It was demonstrated that, according to three climate models MRI-ESM2-0, MPI-ESM1-2-HR, and BCC-CSM2-MR by 2080-2100, under different greenhouse gas emission scenarios (SSPs), a reduction in the area of habitats suitable for R. coelestis will occur in Northeast Asia. The core of the monophagous species' range will be concentrated in the valley broad-leaved forests of southern Primorye and in certain regions of Northern and Eastern China, which may be associated with a sufficient availability of the beetle larvae's primary host plant, Acer tegmentosum.
