Photos of the different stages and phases of the Desert Locust, the most dangerous of all migratory locust species in the world. The Food and Agriculture Organization of the United Nations (UNFAO) operates a global early warning system that monitors the situation and provides alerts and warnings in order to reduce the frequency, duration and intensity of devastating plagues that can quickly wipe out a farmer's livelihood and threaten food security on a national and continental scale. For more information, visit FAO's Locust Watch (www.fao.org/ag/locusts) or contact the FAO Desert Locust Information Service (eclo@fao.org).
