S. nitens is solitary (not gregarious) and non-migratory (sedentary), but under certain conditions can form swarms or outbreaks and cause damage to crops and native plant species.

S.nitens is sympatric with the Central American gregarious locust S.piceifrons (Wlk.). It also is a prolific breeder and distantly related to the African migratory ‘locusts’ that sometimes form large destructive swarms.

This grasshopper species belongs to the Subfamily Cyrtacanthacridinae (Bird Grasshoppers) which are relatively large insects with tegmina usually >30 mm.
