NightSounds I have read on a few occasions, where writers have tried to describe the noise of the tropical night, with the “hum of the cicadas”. The insect sound at night is generally from bush crickets. In August the other main noise at night is from the village fiestas, where very loud dance music is played through the weekend after dark. The thinking behind the nocturnal partying, is probably because it is too hot to sleep, the climax of this, is very loud fireworks at 7am! Cicadas are evident during the hot days and the noise can be quite distracting and more of a scream or screech, than hum.
