First, it looks like swarms of migratory birds above the land surface (Photo: C.Schmullius).Then, the swarms look different and no chirping can be heard (Photo: C.Schmullius).At last, the clouds arrive: millions of brown locusts (Photo: C.Schmullius)! Due to large amounts of rain since 2021, the Northern Cape is seeing worst swarms since decades. See e.g.: https://www.foodformzansi.co.za/watch-uncontrollable-locusts-to-stay-until-winter/
First time also, that we met these things: Armoured Bush Cricket. They cannot fly, therefore they developed impressive armors. (Photo: C.Schmullius)
