Schistocerca gregaria

Desert locusts are primarily solitary but can switch to a swarming mode under certain environmental conditions, typically during periods of drought followed by rainfall. In swarms, they can travel thousands of kilometers, devouring crops and vegetation in their path, causing major agricultural and ecological damage.

Breeding occurs in areas with favorable conditions—usually after rainfall in desert and semi-desert regions. Females lay eggs in the soil, which hatch into nymphs that undergo several molts before becoming adults capable of flight. Their rapid reproduction rates contribute to the large-scale infestations.

Adults can grow up to 5 cm (2 inches) long, with powerful hind legs for jumping and large wings for flight. They have distinctive yellow or brown coloring, with dark markings that help them blend into their environment when not in swarming mode.

Native to North Africa, the Middle East, and parts of Asia, desert locusts have been a threat to crops for thousands of years. Their swarming behavior and ability to travel vast distances have made them a challenge for agriculture and a subject of study in pest control and environmental science.

The desert locust is not currently considered endangered but is categorized as a major agricultural pest, especially in arid regions. Swarm control programs are ongoing in affected areas, involving aerial pesticide sprays and ground control efforts to mitigate crop damage and prevent the spread of swarms.
