ABSTRACT
Observations of Apis mellifera foraging at sapsucker drill holes were made during February 1988 in southwestern Virginia. Foraging bouts were dependent upon tem perature; more bees visited drill holes when ambient temperatures exceeded 10° C. Honeybees did not feed directly at drill holes but collected congealed sap from bark surfaces.
In summary, sapsucker drill holes offer a unique carbohydrate source for over wintering honeybees. Use of this resource is, however, subject to the vagaries of the winter climate. Conditions favorable for winter foraging by honeybees, particularly ambient temperatures above 10° C, may occur on few winter days depending on the region.
