Desert locust

Schistocerca gregaria
Eats: PlantsGrasshoppers and cricketsDeserts and dry places6 legs

The desert locust is a big grasshopper that lives in hot, dry lands. Most of the time it lives alone and nobody notices it. But when there are lots of them, they change colour, grow longer wings and fly together in giant swarms.

Lives in
Deserts and dry lands of North and East Africa, Arabia and southwest Asia
Length
4.5 to 9 cm (1.8 to 3.5 in)
Top speed
about 33 km/h (21 mph)
Flying, estimate
Can it hurt you?
Harmless
Harmless to people. It does not bite or sting, but big swarms can eat the food that farmers grow.
What does it eat?
It eats almost any green plant it can find. A huge swarm can eat whole fields of crops in a day.
