Bumble bee foraging on Fleabane flowers. Possible identities include a uncommon colour variant of the Red-belted Bumblebee (Bombus rufocinctus) or the relatively rare Sanderson's Bumblebee (Bombus sandersoni). Its abdominal colouration was unfamiliar, with its thoracic segments coloured yellow-yellow-black-black-yellow-yellow from T1-T6.

Photographed in Ontario, June 2021.
