The Bombay locust, Nomadacris succincta, is a species of locust found in India and southeastern Asia. It is usually a solitary insect, and it is only in India that it has exhibited swarming behaviour. The last plague of this locust was in that country between 1901 and 1908 and there have not been any swarms since 1927. It is thought that the behaviour of the insects has altered because of changing practices in agricultural land use.
