Bombus fernaldae, the Fernald's cuckoo bumblebee, is a species of cuckoo bumblebee having only males and queens, but no worker bees. The females place their eggs in the nest of the confusing bumblebee (Bombus perplexus) or the red-belted bumblebee (Bombus rufocinctus), which raise the larvae. Fernald's cuckoo bumblebees visit flowers of Potentilla, Rubus, clovers, and goldenrods.{{cite web|url=http://www.fs.fed.us/wildflowers/pollinators/documents/BumbleBeeGuide2011.pdf |title=Archived copy |accessdate=2011-10-28 |url-status=dead |archiveurl=https://web.archive.org/web/20111016031953/http://www.fs.fed.us/wildflowers/pollinators/documents/BumbleBeeGuide2011.pdf |archivedate=2011-10-16 }}, p.94
