Wild Africa - Deserts 浩瀚沙漠 - 7
In spring , the desert undergoes a remarkable 1 transformation 2.
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 3 their insect pollinators.
Some extraordinary relationships have been forged. The bright purple blossoms of Lapeirousia are designed purely 4 to attract the fly with the longest tongue in Africa. As the fly probes for a sip 5 of nectar in the long floral tubes, pollen 6 is dabbed onto its forehead. A smart design, but on a windy day, it's not so easy to hit the target.
Diascia flowers use not nectar but nutritious 8 oils secreted 9 by glands at the tips of their floral tubes to tempt 11 pollinators. Flower and bee, in this case, a perfect fit as the insect dips its toes for oil.
Ignited by the rain, the flowering of the Karoo touches the lives of all its inhabitants. Brandt's whistling rats are quick to harvest the blossoms around their burrows 12.
These desert rats time their breeding to the birth of fresh food, but with snakes around, mothers can't risk leaving their youngsters at home. Clinging to her nipples, they're carried along, a sort of meals on wheels.
