Bumble bees represent one of the most important groups of pollinators. In addition to their ecological and economic relevance, they are also a highly charismatic group which can help to increase the interest of people in realizing, enjoying and conserving natural systems. However, like most animals, bumble bees are sensitive to climate. In this atlas, maps depicting potential risks of climate change for bumble bees are shown together with informative summary statistics, ecological background information and a picture of each European species. Thanks to the EU FP7 project STEP, the authors gathered over one million bumblebee records from all over Europe. Based on these data, they modelled the current climatic niche for almost all European species (56 species) and projected future climatically suitable conditions using three climate change scenarios for the years 2050 and 2100. While under a moderate change scenario only 3 species are projected to be at the verge of extinction by 2100, 14 species are at high risk under an intermediate change scenario. Under a most severe change scenario as many as 25 species are projected to lose almost all of their climatically suitable area, while a total of 53 species (77% of the 69 European species) would lose the main part of their suitable area. Climatic risks for bumblebees can be extremely high, depending on the future development of human society, and the corresponding effects on the climate. Strong mitigation strategies are needed to preserve this important species group and to ensure the sustainable provision of pollination services, to which they considerably contribute.

Ce guide constitue le premier volume d’une série sur les Hyménoptères d’Europe. Dans sa première partie, une présentation générale est proposée sur leur morphologie, leur écologie, leur évolution et les méthodes pour établir une collection de spécimens. Nous proposons aussi une clé de détermination pour l’ensemble des superfamilles recensées sur le continent européen. Le guide développe ensuite une synthèse des connaissances sur les abeilles sauvages d’Europe et des régions limitrophes, en tenant compte des dernières avancées scientifiques. Cette diversité se décline en plus de 2000 espèces réparties en 77 genres sur tout le territoire couvert par cet ouvrage. L’ouvrage aborde la biologie, la morphologie, l’écologie et la conservation des abeilles sauvages d’Europe. Il propose, pour la première fois, une clé d’identification illustrée des 77 genres, ainsi qu’un inventaire exhaustif des espèces et une description complète d’abeilles sauvages représentatives au sein de chaque genre (morphologie, écologie, distribution). Un guide de référence complet, accessible aux non-spécialistes, à emporter partout pour découvrir l’étonnante diversité de ces pollinisateurs indispensables !
