International audience In recent decades, several animal and plant species have been in regression (population size decrease and geographical distribution shrinking). This loss of biodiversity can be due to various factors such as the destruction and fragmentation of habitat, urban development, pesticides or climate change. However, some species benefit from these changes and expand their distribution. Here we report observations (in 2013 and 2014) of two Euro-Mediterranean bumblebee species: Bombus terrestris for the first time and Bombus lapidarius, north of the Arctic Circle in Fennoscandia.

Résumé Ces dernières décennies, de nombreuses espèces animales et végétales sont en régression autant d'un point de vue de leur distribution qu'au niveau de leur effectif de population. Cette perte de biodiversité peut être due à différents facteurs comme la destruction et la fragmentation de l'habitat, le développement urbain, les pesticides ou encore le changement climatique. Néanmoins, certaines espèces profitent de ces perturbations pour étendre leur distribution. C'est ainsi que pour la première fois, deux espèces Euro-Méditerranéennes de bourdons (B. terrestris et B. lapidarius) ont été observées en 2013 et 2014 en Fennoscandie au-delà du Cercle Arctique.
