hypnorum is the newest Bumble Bee species to
colonise the UK, first arriving in 2001. It has rapidly
spread north and finally reached Nottinghamshire in 2009,
where it was first recorded from Worksop. Other
Nottinghamshire records quickly followed in the early
part of 2010, before we found what is believed to be
Nottinghamshire's fifth record, at Gamston Wood near
Retford in July 2010. Its spread has continued at an
astonishing rate and it has quickly become common
throughout Nottinghamshire, so much so, that we think
that Bombus hypnorum is very fast becoming the
commonest Bumble Bee now.
Having two broods a year has certainly
helped its spread, with new queens appearing in June.
Bombus hypnorum is a distinctive tri-coloured and
easily recognised Bumble Bee, that stands out clearly
from the much commoner Bombus pascuorum.
