Increased tactile stimulation of the hind legs causes an increase in levels of serotonin. [ 4 ] This causes the locust to change colour, eat much more, and breed much more Introduction. Uvarov (, ) proposed the phase theory to explain the origin and decline of locust plagues, 6 years after he had observed migratory locusts (Locusta migratoria migratoria, L.)

These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming taxonomic distinction is made between locust and (insect).
