Research on coprophagous beetles of the Hydrophilidae family in the Polish Carpathians was conducted from 2011 to 2013. The beetles were caught using baited traps. The research sites were selected to take into account both the horizontal diversity of habitat conditions and the vertical diversity associated with elevation above sea level. During the study, 9589 coprophagous hydrophilid individuals were collected, representing 17 species and five genera. Two species that were new to Poland were found: Cercyon tatricus and Pachysternum capense. The vertical ranges of the individual species of coprophagous hydrophilid beetles within the Polish Carpathians were determined as well as the elevations above sea level, with the highest and lowest species richness of this group of insects. The capture of Pachysternum capense in the Tatra Mountains may indicate the existence of an unrecognized path of migration of small insects from Southern to Northern Europe. The route and mechanisms of their migration are discussed.

在波兰喀尔巴阡中分布的共食性亲水甲虫（鞘翅目，亲水科，Sphaeridiinae）。

从2011年到2013年，对波兰喀尔巴阡山脉嗜水菌科的共生甲虫进行了研究。使用诱饵诱捕器捕获甲虫。选择研究地点时要考虑到栖息地条件的水平多样性和与海拔以上高度相关的垂直多样性。在研究过程中，共收集了9589种共食性亲水性个体，分别代表17个物种和5个属。发现了两个波兰新物种：cercyon tatricus 和Pachysternum capense。确定了波兰喀尔巴阡山脉中的共生亲水甲虫的单个物种的垂直范围以及海拔高度，这组昆虫的物种丰富度最高和最低。在塔特拉山中捕获的Pachysternum capense可能表明存在小昆虫从南欧向北欧迁移的未知途径。讨论了它们的迁移途径和机制。
