The locusts now transform into winged adults,
and with conditions as good as this, they do so three times faster than normal.
Now they are at their most voracious...
and with wings, they can take to the skies.
Once airborne, the locusts can travel over 60 miles a day in their search for new feeding grounds.
A super swarm of this scale may only appear once in a decade.
This one extends over 200 square miles and contains several billion individuals.
Between them, they will devour 40,000 tonnes of food in a day.
Nothing can strip a land of its vegetation with such speed and thoroughness as a plague of locusts.
When the food eventually runs out, the whole army will die...
but not before it's devastated the land.
