Abstract
Bumblebees and other aculeate Hymenoptera were observed collecting a secret ion associated with galls of Callirhytis operator (Cynipidae) on acorns of Red Oak (Quercus rubra) at Lake Matchedash, Ontario, in August 1996. This i s the first record of bumblebees collecting gall secretions, which may be a locally important sugar source during mast years.
