In Yemen, locust numbers remain low along the Red Sea coastal plains where scattered adults are maturing and small-scale breeding may occur in localized areas of recent rainfall.

Locusts differ from other grasshoppers in their ability to change from a solitary living form into gregarious, highly mobile, adult swarms and hopper bands, as their numbers and densities increase. They exist in different states known as recessions (with low and intermediate numbers), rising to outbreaks, and extremely high densities or plagues. Adult locusts differ more in form than in colour. The solitary phase has shorter wings, longer legs, and a narrower pronotum, or dorsal sclerite (with higher crest and larger head), than the gregarious phase. The adult of the gregarious phase has a more saddle-shaped pronotum, broader shoulders, and longer wings.
