description Locustana pardalina Overview

Locustana pardalina, known as the brown locust, is a significant agricultural pest native to the semi-arid Karoo region of South Africa. The species exhibits phase polymorphism, meaning it can transition from a solitary grasshopper into a gregarious, swarming locust under favorable environmental conditions. Following periods of drought-ending rain, population explosions produce highly destructive swarms that migrate across southern Africa. These swarms cause extensive damage to cereal crops and grazing lands.

help Locustana pardalina FAQ

Where does the Locustana pardalina grasshopper live?

The Locustana pardalina, commonly known as the brown locust, is endemic to the semi-arid Karoo region of South Africa. During severe outbreaks, their swarms can spread rapidly across southern Africa, causing significant agricultural damage.

How does Locustana pardalina damage crops?

Locustana pardalina damages crops and rangeland through massive, destructive swarms that emerge during periodic population explosions. These locusts consume massive amounts of vegetation, devastating grain crops and pastures across southern Africa.

What is the difference between the solitary and gregarious phase of Locustana pardalina?

Like many locust species, Locustana pardalina can change its behavior and morphology between a harmless solitary phase and a destructive gregarious phase. The shift to the gregarious phase is triggered by crowding, which leads to the formation of the massive swarms that threaten crops.

When do Locustana pardalina swarms typically occur?

Swarms of Locustana pardalina occur following favorable weather conditions in the Karoo, often tied to periods of drought followed by rain. These periodic population explosions allow the locusts to multiply rapidly and form destructive swarms.
