Experienced foragers routinely fly their "beeline"
between hive and food while orienting by landmarks. Newly recruited
bees previously exposed to food and locality odors present on
dancers in the colony leave the hive and have been observed to
fly in an ever-expanding spiral path After they get downwind
from the appropriate food source and/or aerial pathway of foragers,
they can perceive target odor molecules and proceed upwind in
a zigzag flight as long as they continue to detect those molecules.
If odor contact is lost, they "cast" until they are
once again within the odor plume (full details in Wenner and
Wells, 1990:chap. 5, excursus OS). |
