Submit a sighting of a winter bumblebee

Reporting your sightings of winter bumblebees 2019/20


BWARS is continuing its long-term project throughout the winter of 2019-2020, in which we are plotting and monitoring the spread and behaviour of winter active Bombus species in Britain.

If you have any records of either Bombus terrestris or B. pratorum between 1 November 2019 and 1 March 2020, please submit the full details via this online recording platform. There is a facility for uploading photographs to support records if you have them. Please use the boxes below to provide information on numbers, sexes, flower visitation, behaviour and nest sites, and include any additional information in the "Comment" section.

NB If anyone finds winter active bumbles of any other species, please can these be reported via iRecord (remember to include a photo for verification purposes). iRecord is accessible here
