But we have learnt that they often hide beneath stalks and leaves,” Mr Lesaigor said. This means that the locusts may have changed their behaviour as a survival tactic. “For now, we suspect that hot and sunny conditions are forcing them to hide under green matter,” Mr Lesaigor said. When the environment is favourable, often after heavy rains and cyclones, the locusts converge and change colour to pink (immature) and then yellow (mature) and form swarms. Desert locusts, unlike many grasshoppers, can travel over long distances and change habits and behaviour.
