The aim of the study is to present all distribution sites of Bombus semenoviellus in Poland reported between 1988 and 2019. The increase of species dispersion was concluded, especially in the central part of the country, as well as the occurrence in the high Karkonosze and Tatry mountains. This is likely the effect of progressing climate change, as well as the increase in climate continentalism in Europe. Differences between summer and winter temperatures favour the spread of this Siberian bumblebee species throughout the continent. Many specimens were found on plants originating from its central and west Asia. Those plants also occur in eastern and central Europe which could have helped this bumblebee spread west throughout Europe. B. semenoviellus will increase its range towards Western Europe. Based on observations so far, it is not possible to determine its invasive features and increased competitiveness for food and nesting places in relation to other bumblebee species.
