Rusty-patched Bumble Bee
Bombus (Bombus) affinis Cresson, 1863

New York State Distribution [-]
The rusty-patched bumble bee has not been confirmed in New York since 1999. Due to this and its rapid, recent decline throughout much of its range, its current status in New York is state historical (SH). 

Global Distribution [-]
The historic range for rusty-patched bumble bee includes Maine westward to Minnesota including southern Canada and southward in the United States to North Carolina and Tennessee. The current range for this species is undetermined, as due to its rapid, recent decline, records pre-2006 may now be considered historical. The probable extant core area appears to be centered around Illinois, Wisconsin, Minnesota, and Ontario, but any populations are localized within these states and provinces, if they persist (NatureServe 2015).
