A paucity of genetic information and the drastic decline in population size beetle Cerambyx cerdo has made this species a high priority for research conservation management. The state-listed beetle, saproxylic insect associated with oaks, discontinuous range, larger more connected populations southern Europe small isolated continent's central northern parts. Here, we used seven microsatellite loci one DNA fragment mitochondrial gene COI to examine structure, diversity, contemporary flow between two Polish beetle. viability analysis summarizing collected data as well field records species-specific was performed investigate probability populations' persistence over 20 years under different simulation scenarios. Genetic drift due spatial isolation bottleneck(s) is probably major evolutionary force responsible low number haplotypes lower diversity these compared neighboring Czech populations. Despite large geographic distance populations, differentiation them low, which could reflect shared ancestral polymorphism stochasticity retained alleles rather than homogenizing effect flow. Differences among probabilities extinction were detected and, worst-case scenarios, will disappear within four generations. Conservation efforts must focus on supplementation, habitat restoration, post-release monitoring. results our study provided that can be incorporated into future management actions aid
