Abstract
Further studies of the pollen constancy of hive bees and the wild bee visitors to apple blossoms, in continuation of those previously published (1, 2) are reported. Only hive bees and various Andrena spp. appeared in significant numbers in this study. The latter show a much lower degree of constancy than the former, confirming previous work. The wide difference between the complex of insect pollinators at Macdonald College and that of Kings County, Nova Scotia, is discussed. The highly polytrophic character of the common insect pollinators of the apple is emphasized.
