Résumé : Little is known about phase polymorphism of the red locust, Nomadacris septemfasciata (Audinet-Serville, 1838) in Madagascar despite its economic importance. Gregarious forms of this locust had never been recorded until now on the island, only solitarious and transient forms. The recent worsening of outbreaks provided an opportunity to study phase polymorphism under experimental and field conditions.
