After reading a report by a well known botanist, Arnold Menke wondered (Sphecos 16:11, 1988) what species he referred to with “…billions of semi-dormant hibernating wasps covering the trees” in Eastern Venezuela. During a recent visit to Venezuela, diapausing wasps were collected at three localities in the Northern Cordillera (ca. 2,400 m) during the dry season (November to April). Mass aggregations of wasps were using man-made constructions, vegetation, and natural crevices for shelters. Some wasps made occasional flights out of the group at warm hours of the day to collect nectar and they later engaged in trophallaxis with other wasps. No nesting activity occurred at this locality and season. The species to which Menke referred was clearly Polistes versicolor.
