Scientists say they may have discovered the reason why swarms of locusts are driven to devour such huge quantities of vegetation. They suggest that locusts combine into swarms because they are frightened of being eaten by each other. The findings by researchers from the US, UK and Australia were published in the journal Current Biology. A swarm can contain billions of insects and eat tens of thousands of tonnes of vegetation in a single day.
