The chicharra is the common name in Spanish-speaking countries for the cicada, an insect whose loud summer song is closely associated with heat, holidays and rural life. Because the sound is instantly recognisable even without a picture, creators reuse clean cicada recordings as a shorthand for summer, stillness and the outdoors in videos, podcasts and soundboards. It has no single viral origin, instead it survives as a practical nature effect, valued for how quickly it sets a season and a place.
