description Dociostaurus maroccanus Overview

Dociostaurus maroccanus, widely known as the Moroccan locust, is a species of grasshopper that functions as a major agricultural pest across the Mediterranean, the Middle East, and Central Asia. The insect is notorious for its swarming behavior, which poses a severe threat to food security by defoliating and destroying extensive fields of wheat, barley, and other cereal crops. It typically inhabits arid and semi-arid zones, where outbreaks are highly dependent on specific climatic conditions, particularly irregular rainfall patterns. The geographical range of this destructive pest extends from Morocco and North Africa as far east as Afghanistan.

help Dociostaurus maroccanus FAQ

How can I identify a Moroccan locust?

Dociostaurus maroccanus usually has a pale cross-shaped marking on the pronotum and red hind tibiae. Solitary and gregarious adults can differ in color and body proportions, so the cross marking is particularly useful.

Is the Moroccan locust found only in Morocco?

No. Its range extends from the Canary Islands and Madeira across North Africa, southern Europe, the Middle East, and into Central Asia as far as Kazakhstan and Afghanistan.

What crops does Dociostaurus maroccanus damage?

It is a polyphagous pest that can consume cereals, pasture plants, legumes, and other crops. Dense hopper bands and adult swarms can strip vegetation across both farmland and grazing areas.

What causes Moroccan locusts to form swarms?

Crowding in suitable breeding habitats triggers a shift from the solitary phase toward the gregarious phase. Successful egg hatching after favorable weather can produce dense nymphal bands that later develop into mobile adult swarms.
