The general color is yellowish green to light brown with mottled areas on the pronotum and tegmina. Females are 36-54mm and the malesare3s-44mm.Adult swarms roost within un-harvested maize

The red locust, Nomadacris septemfasciata ( lngwelebovu)

The base of the under wing is red or sometimes purple, more visible when flying. This locust has a small spur on the throat. Only one generation is produced a year with adults living for some 8-9 months. Eggs are laid with the first rains (September- October) and hopper development takes 3-4 months during the summer rainy season.
