Large garden bumblebee : ウィキペディア英語版 | Large garden bumblebee
''Bombus ruderatus'', or the large garden bumblebee, is a species of long-tongued bumblebee found in Europe and in some parts of northern Africa. This species is the largest bumblebee in Britain and it uses its long face and tongue to pollinate hard-to-reach tubed flowers. Bumblebees are key pollinators in many agricultural ecosystems, which has lead to ''B. ruderatus'' and other bumblebees being commercially bred and introduced into non-native countries, specifically New Zealand and Chile. Since its introduction in Chile, ''B. ruderatus'' has spread into Argentina as well.〔 Population numbers have been declining and it has been placed on the Bioadversity Action Plan to help counteract these declines. == Taxonomy and phylogeny == ''Bombus ruderatus'' is part of the order Hymenoptera and the family Apidae. ''B. ruderatus'' is in the genus Bombus and is one of 239 species of bumblebees, with 23 of those existing in Britain alone. ''B. ruderatus'' is part of the subgenus Megabombus, along with ''Bombus hortorum''.〔 ''B. ruderatus'' is most closely related to ''B. hortorum''.〔
