Many thanks to Steven Falk for permission to use his images of some of the species which we did not have access to – and for records and advice. Deepest thanks to Matt Miles and Blooms for Bees for permission to use the bee artworks. Many thanks to Mike Edwards, Stuart Roberts, Matt Smith and all involved at BWARS (Bees, Wasps and Ants Recording Society) for advice and information on many of the species involved and for suggested literature sources. And of course – last and by no means least – many thanks to all the recorders of bumblebees in Cumbria, past and present. In this respect, thanks to Tullie House Museum for providing support, resources and access to historic records. The great efforts of many past and present entomologists and natural history enthusiasts has provided a comprehensive overview of the historical status of bumblebees in Cumbria, despite considerable challenges presented by the size and terrain of the county, taxonomic difficulties and the simple fact that – historically at least – many entomologists did not tackle bumblebees with any enthusiasm (the reasons for which will be discussed in the next section). In the north of Cumbria, George B. Routledge and Frank H. Day provided a baseline of early records, with additional records from Harry Britten (who went on to become a very well-known entomologist and Curator of Entomology at Manchester Museum), and James Murray. In the south, James Davis Ward was a source of accurate records around Grange and Albert Edward Wright covered the same area with considerable effort until 1950.

The late, great, Neil Robinson was an aculeate specialist and not only recorded avidly and widely but also summarised the status and distribution of bumblebees (in addition to all aculeate bees, wasps and ants) in his “List of the bees, wasps and ants of Cumbria. Records to the year 2005”, which was – effectively – a Checklist / Atlas hybrid, such was the detail of aculeate species described. In more modern times, Stephen Hewitt (previously, Keeper of Natural Sciences at Tullie House Museum) and Michael Archer must be commended for continued recording of bumblebees as resident and visiting entomologists respectively. Vivian Russell, Jane Orgee, Carolyn Postlethwaite, Charlotte Rankin, Tanya St. Pierre, Nick Franklin and Ryan Clark have – in addition to working directly on this project – provided a huge number of records which has greatly increased and clarified the known status and distribution of bumblebees in Cumbria to the present day. Also, a great thanks to many colleagues from Lancashire WT and Cumbria WT (plus affiliated folk) who have kindly granted permission to use several photos throughout the Atlas.
