This study analyses the bark beetle species spectrum (Scolytinae) in supranational migration across the Czech Republic (2020–2025) using a Johnson-Taylor suction trap network. Out of 2 129 identified individuals (45 species), Pityogenes chalcographus (Linnaeus, 1761) and Crypturgus cinereus (Herbst, 1793) were dominant, with their 2021 outbreak temporarily altering the community's proportional abundance. Ecological indices (H', J') confirmed an acute internal asymmetry caused by massive pest flights. The findings support the dispersal flight phenomenon, where individual scattering into vast air volumes explains the high proportion of sub-recedent species without compromising the representative value of the samples. The proven efficacy of suction traps for invasive species detection led to their official integration into the Czech national phytosanitary surveillance system.
