Bands

Bands

Desert Locust hoppers (wingless nymphs) that form a band. Immature and mature individuals in the gregarious phase form bands which feed, bask and move as cohesive units.

At the point when plentiful rain falls and yearly green vegetation grows, Desert Locusts can increment quickly in number and, inside a month or two, begin to concentrate and become gregarious.

When the hoppers become gregarious, their colouration changes from largely green to yellow and black. Their bodies become shorter, and they give off a pheromone that causes them to be attracted to each other. Except if checked, this can prompt the formation of little gatherings or bands of wingless hoppers and small groups or swarms of winged adults. This is called an outbreak and usually occurs within an area of about 5 000 km2 (100 km by 50 km).
