Passion Flower and the Bee

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.
