 When the density of hoppers reaches a critical level, they band together and move as a group of sometimes many thousands. When they take to the wing, they form swarms as large as several square kilometres. The swarms can travel for over a thousand kilometres and when a swarm lands on a food crop, it can destroy the crop completely. © Copyright D G Mackean |
