Migratory Locust - Haradh

Whilst at Haradh I saw a Migratory Locust Locusta migratoria in a large pivot irrigation field. Normally they occur in small numbers throughout Arabia, but rarely form into swarms. There are two colour forms, brown and green with the green colour forms mainly solitary adult females. Under favourable breeding conditions they can form into vast groups, with young ‘hoppers’ often all marching in the same direction. They are very strong fliers and migratory specimens have been recorded as far away as Great Britain. The migratory locust is the most widespread locust species in the world, and the only species in the genus Locusta. It occurs throughout Africa, Asia, Australia and New Zealand.
