Sementara itu wabah belalang terbesar selama bbrp dekade menyerang Afrika, melewati somalia, ethiopia, kenya... ga jelas ntar terbang kemana lagi, menghabiskan tanaman disetiap tempatnya lewat.
Belalang.. belalang, milyaran belalang.. dimana2..
Belalangnya berwarna kuning.. pernah lihat? pernah makan?
Permukaan tanah, penuh belalang, mewabah di area yg luas.

Puluhan tahun tidur, sekarang bangun..
Belalang2 ini bisa menghancurkan perekonomian negara Afrika Timur.

Bro Setyo, belalang menjadi wabah bukan krn kekurangan predator. Tetapi perubahan bentuk (morphologi) secara serentak. Jadi belalang umumnya muncul sendiri, namanya fase menyendiri. Tetapi perubahan hormon membuat mrk bisa jadi hewan mengelompok.
Inilah belalang. Dulu ada yg mengira kedua fase belalang itu 2 jenis species yg berbeda. Ternyata sama. Umumnya belalang ada pada fase soliter, ga mengganggu. Tapi ketika mrk serentak jadi fase massa perusuh, mrk berubah warna dan mulailah bikin masalah.
Ga jelas bahasa Indonesia ada bedanya ga istilahnya. Tapi bahasa Inggris ada. Yg fase solitaria (sendirian) namanya GRASSHOPPER, sedangkan yg fase gregaria (mengelompok mengganas) namanya LOCUST.

Grasshopper dan Locust itu binatang yg sama, cuma beda fase, beda kelakuan.
