Siberian cricket (Aeropus sibericus)

During the great glacial periods, this orthoptera lived on the plains. As the climate has warmed back up, it has moved to the high mountains, above 2000m. The male can be recognised thanks to the its bulging back legs, hence its surname of “Popeye”. This herbivore, whose predators include birds, marmots and foxes, is part of the food chain in high-altitude pastures.
