It occurs in most of Africa south of the Sahara Desert, but its main breeding ground, and the original source of most plagues, is on the floodplains of the Niger River in West Africa. Much of the time this locust adopts a solitary lifestyle, but under certain conditions it becomes gregarious; the young nymphs, known as hoppers, form bands that move together and the adult insects form swarms that may reach plague proportions. Plagues of this locust took place from 1891 to 1903 and again from 1928 to 1941. After many years without outbreaks of the insects, further plagues occurred in the last two decades of the twentieth century. ==Description== The African migratory locust has two phases, a solitary one, where the insects behave independently, and a gregarious phase where they gather together and act as a cohesive unit. Adult insects differ morphologically between the two phases; solitary insects have an arched prothorax, the foremost segment of the thorax, and are either green or brown, darkening in colour as they mature (especially the abdomen of the female). Gregarious insects have a flatter prothorax and are a pale tan or a greyish colour with dark markings. As they mature they become duller in appearance and the males may become more yellowish. The hoppers are also different in the two phases. The newly hatched solitary hopper is grey, but later stages can be a variety of colours including green, buff, brown, red, grey and black. Their colouring tends to match their surroundings, so on new, young foliage they are green and after wildfires they may be black. The gregarious hoppers are boldly marked in a pattern of brown and black.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Locusta migratoria migratorioides」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
