Notes.
No recent specimens examined.
Bombus pensylvanicus
is evidently a declining species in the northern extent of its historical range (
Grixti
et al.
2009
), but is still commonly seen in the south and western part of its range (
Cameron
et al.
2011
; many recent records at http://bugguide.net/node/view/65631).
