Abstract

jats:titleAbstract</jats:title>jats:pThis study examined shifts over a 35-year period in the phenology of the four most important bumblebee species (jats:italicBombus terrestris</jats:italic>,jats:italicB. lapidarius</jats:italic>,jats:italicB. pascuorum</jats:italic>andjats:italicB. hortorum</jats:italic>) in Central Europe. The species showed similar temporal trends, significantly advancing components of their main flight period in association with rising temperatures such that, for example, mid-dates of the main flight period advanced by 10–23 days over the study period. Drivers of this change differed between the four species. Trends in, and drivers of, the timing of first queens, first workers and first males were less consistent. Aspects of the phenology of the least common species,jats:italicB. hortorum</jats:italic>, were up to a month earlier than the other species and climatic effects less clear cut. There were some suggestions of differences between species trends. These results stress the importance of considering changes and drivers of change for thejats:italicBombus</jats:italic>family on a species-specific basis with the need to pay more attention to the life history traits of the study organisms.</jats:p>
