Phase 1 - stigmas up |
Phase 2 - stigmas down |
The movie above shows a bee collecting nectar from a newly opened flower that still had the stigmas in the upright position. The hair on the bee's back became covered with pollen from the downward facing anthers but the bee never made contact with the upward facing stigmas. |
This movie shows the same bee from the phase 1 flower
when visiting another flower that had already turned its stigmas into
the downward orientation. With the stigmas bent over the bee's back rubs
the stigmas while continuing to forage for nectar. Since the its back
was covered with pollen from other flowers, pollen is easily transferred.
