Within a month, the spring blooms are finished. The plants now set their seeds, taking advantage of the warm summer winds which sweep the desert.

For a while, the karoo just glows.

But trouble is stiring. Triggered by the rains, an all-devouring army-- locusts2.

Millions emerge from eggs buried in the sand, gathering3 into columns which may stretch for ten kilometers. At this stage, they can't fly, only hop4, but it doesn't hinder their progress. These sweeping5 hordes devastate7 any fresh growth in their path.

After five weeks of steady munching, the infantry9 becomes airborne. These breeding swarms10 can cover up to 80 kilometers a day, but only while the food and moisture last.

So how do you define a desert in Africa? They are places where less than 50 centimeters of rain falls a year. Neighbouring the karoo is a desert which gets the maximum, in brief, but intense summer monsoons.
