Description: The approximate range of Yellow-banded bumble bee (Bombus terricola)was created by Joanna Wilson and Bonnie Fournier in October 2015. Range in the U.S. was sketched around the records of Bombus terricola mapped in the COSEWIC 2015 draft status report on yellow-banded bumble bee. The Canadian range is based on specimen records of Bombus terricola up to 2013 in the unpublished database ‘Bumble bees of North America’provided by Leif Richardson (afull list of contributors to the database can be found at http://www.leifrichardson.org/bbna.html). Additional 2014 records from southeast Yukon were provided by Syd Cannings and Jenny Wu. Note that the colouration of Bombus terricola can be very similar to Bombus occidentalis where the two species overlap therefore there is some uncertainty in species identification; the identification of records around Vancouver and on Vancouver Island B.C. should be verified (Cory Sheffield pers. comm. Oct 2015). The range was updated in December 2019 using new recorded observations in Inuvik provided by Syd Cannings. The northern NWT part of the range is based on an EBAR (Ecosystem-based automated range mapping) range created by Suzanne Carriere, ENR and Natureserve Canada. The EBAR range polygon was smoothed using the ArcMap 10.6 Cartography tool.
