A plague of insects refers to a large number of insects that suddenly appear and cause destruction to crops, plants, or livestock in an area. These swarms can have a serious impact on agriculture and ecosystems, leading to widespread damage and economic losses. Control measures like pesticides and habitat modification may be necessary to manage plague insects.
Many insects travel in swarms - including (but not limited to) bees, flies, grass-hoppers, locusts, moths & butterflies.

Locusts themselves do not directly kill people; they are herbivorous insects that primarily consume vegetation. However, swarms of locusts can devastate crops, leading to food shortages and famine in affected areas, which can indirectly result in loss of life. The impact of locust swarms on agriculture and food security can have serious consequences for vulnerable populations, particularly in regions already facing challenges.
