Hints: the Garden of Africa pollinator Lapeirousia probe nectar pollen dab 本文有一个破折号 --
In spring , the desert undergoes a remarkable transformation. For just a few weeks a year, the flowers of over 3, 000 different plant species turn this desert into the Garden of Africa. This dazzling variety of color has evolved over time for a very special purpose -- for plants to seduce their insect pollinators. Some extraordinary relationships have been forged. The bright purple blossoms of Lapeirousia are designed purely to attract the fly with the longest tongue in Africa. As the fly probes for a sip of nectar in the long floral tubes, pollen is dabbed onto its forehead. A smart design, but on a windy day, it's not so easy to hit the target.
