The preliminary comparison of the groups of beetles from the Ceramdycidae in different areas of the Western Beskid Mountains was based on many years of observation and research held in the Babiogórski National Park (BNP), Gorczański National Park (GNP), and Experimental Forestry Facility (EFF) in Krynica. It is worth mentioning that since the study commenced, 62 Cerambycidae species have been observed in the Babiogórski NP. Its area is the only place where Pachyta lamed (L.), Pseudogaurotina excellens (B RANCS.), and Euracmaeops septentrionis (T HOMS.) have been spotted. The occurrence of another four species, namely Brachyta interrogationis (L.), Pachydodes erraticus (D ALM .), Mesosa curculionoides (L.), and Mesosa nebulosa (F.), requires confirmation from the BNP. Gorczański NP is inhabited by 54 Ceramdycidae species, two of which (Cornumutila lineata (LETZ.) and Molorchus kiesenwetteri M ULS. et REY) have not been found in the other two investigated locations. The EFF in Krynica houses 94 species, with the following ones having been recorded exclusively from this area: Acanthocinus aedilis (L.), Acanthocinus reticulatus (R AZUM .), Anastrangalia dubia reyi (H EYDEN), Arhopalus ferrus (M ULS.), Chlorophorus herbstii (B RAHM ), Clytus arietis (L.), Cortodera femorata (F.), Cyrtoclytus capra (G ERM .), Ergates faber (L.), Exocentrus lusitanus (L.), Grammoptera abdominalis (STEPH.), Leptura aethiops P ODA, Monochamus galloprovincialis (O LIV.), M. saltuarius occidentalis SLÁMA, Nivellia sanguinosa (G YLL.), Oberea erythrocephala (SCHRANK), Phymatodes glabratus (CHARP.), Plagionotus arcuatus (L.), P. detritus (L.), Pogonocherus decoratus FAIRM ., P. hispidulus (P ILL. et M ITT.), Rhagium bifasciatum F., Rhamnusium bicolor (SCHRANK), Ropalopus macropus (G ERM .), Rosalia alpina (L.), Saperda carcharias (L.), S. perforata (P ALL.), Stenocorus meridianus (L.), Stenopterus rufus (L.), Stenostola ferrea (SCHRANK), Stictoleptura tesserula (CHARP.), Strangalia attenuata (L.) and Tetropium gabrieli W EISE. Comparing the distribution of longhorn beetles from the above-mentioned mesoregions, it can be confirmed that Pronocera angusta (K RIECH .), Tetrops starkii CHEVR ., Anisarthron barbipes (SCHRANK), Pyrrhidium sanguineum (L.), and Ropalopus clavipes (F.) were recorded only from the Beskid Żywiecki Range (outside of BNP). The Beskid Sądecki Range (outside of EFF) houses solely Anaesthetis testacea (F.), Anoplodera sexguttata (F.), Lamia textor (L.), Oplosia cinerea (M ULS.), Phytoecia cylindrica (L.), and Ph. virgula (CHARP.), whereas Exocentrus stierlini G ANGLB ., Phymatodes alni (L.), and Xylotrechus antilope (SCHÖNH.) were found only in the Beskid Wyspowy Range. A further intensive study in the Wieliskie and Wiśnickie Foothills and the Rabczańska and Sądecka Basins might lead to more species being discovered. It is probable that Deilus fugax (O LIV.), Phytoecia coerulescens (SCOP.), and Phytoecia pustulata (SCHRANK) may be found in farming wastelands, by road side, and near rail embankments. Woodlots, unkept parks, oak forests, and abandoned orchards could possibly house Axinopalpis gracilis (KRYN.), Grammoptera ustulata (SCHALL.), Leioderes kollari (REDTB .), and Menesia bipunctata (ZOUBK.), while spruce forests might be inhabited by Semanotus undatus (L.). The changing climate might also lead to the migration of Stenurella septempunctata (F.), Leptura aurulenta F., and Pachytodes erraticus (D ALM .) from Slovakia through the Moravia Gate, the Poprad River Valley, or Tylicka Mountain Pass. The Cerambycidae are the beetles whose larval stage of life is closely connected with bark, vascular cambium, phloem, and the wood of trees and shrubs. Some species, in their insect stage, subsist on nectar, pollen, and other parts of plants. The variety of biotopes in the forests of the Beskid Zachodni Mountains creates perfect conditions for the development of many rare longhorn beetle species. Large forest complexes, such as the Karpacka Forest, expedite the migration and exchange of genes between the existing species. The Babiogórski NP, Gorczański NP, and EFF are the regions that have been thoroughly studied and inventoried, while the Beskid Mały, Beskid Sądecki, Beskid Makowski, and Beskid Wyspowy ranges as well as Wiślickie and Wielickie Foothills still require further research and observation. Despite the high number (148) of species recorded in these regions (ŁUSZCZAK and STARZYK 1982, B URAKOWSKI et al. 1990, G UTOWSKI 1995, S ZAFRANIEC et al. 2021), further chorological and ecological research on the Cerambycidae is needed, as they constitute great importance for forest ecosystems. It is also necessary to define protective measures for species protected by law as well as methods of dealing with endangered and nearlyextinct species.
