Bombus ruderatus (Scares) Lode

This bumblebee was once very common in
southern and central England but it has been lost
from over 80% of its known localities over the last
100 years. In the UK it is now mainly found in the
Fens, East Midlands and Cambridgeshire.
Reasons for decline
Agricultural intensifi cation as well as forestry and
development have all resulted in the loss of large
areas of fl ower-rich grassland, wet grassland
and ditches, which has been the main cause of
decline in this species. There were once large
areas of fl ower-rich unimproved habitat,
however these habitats are now small
and are still being lost.
Habitat
The Large garden bumblebee is
mostly associated with fl ower-rich
meadow land and wetlands. It has survived
successfully in the fens and river valleys of
eastern England; however it also uses
intensively farmed areas with fl ower-rich
ditches, fi eld margins or organic clover leys. It is
vital that pollen and nectar sources are available
within foraging distance of nests from April to
September. It needs disused burrows of small
mammals for nesting sites; these are also believed
to be where the queens hibernate over winter.
