Cigarra is the Spanish and Portuguese name for the cicada, an insect famous for the loud buzzing calls males make in warm weather by vibrating membranes on their abdomen. Because that call is so closely linked to summer heat across southern Europe and Latin America, the short clip circulates on soundboards as a ready made nature cue. Creators reach for it when a scene needs heat, countryside or an uneasy quiet without showing the insect itself, and it has become a familiar shorthand in memes, edits and casual videos.
