How do cicadas make noise? PJ Liesch holds up a male 17-year cicada and shows the tymbal under its wings. The tymbal is the small white section of the insect with thin, black lines.
Brevisana brevis, known as the shrill thorntree cicada, is a cicada found in Africa and is likely the loudest insect on record. It has been recorded producing sounds with pressure levels of 106.7 decibels at a distance of 50 cm. [1] [2] Brevisana brevis is found in the African countries Angola, Zimbabwe, South Africa, and Malawi. [3]
Males disable their own tympana while calling, thereby preventing damage to their hearing; [45] a necessity partly because some cicadas produce sounds up to 120 dB (SPL) [45] which is among the loudest of all insect-produced sounds. [46] The song is loud enough to cause permanent hearing loss in humans should the cicada be at "close range". In ...
The earliest reports of 17-year cicadas came from the 17th century. While the cicadas may be a nuisance to some nowadays, for people a few hundred years ago, the bugs were truly terrifying.
The earliest fossils of cicadas more closely related to Cicadidae than to Tettigarctidae date to the Jurassic period. The morphology of well preserved stem cicadids from mid-Cretaceous Burmese amber from Myanmar suggests that unlike many modern cicadas, they were either silent or only made quiet sounds. [2] The oldest modern cicadids date to ...
The buzzing bugs emerged in April, but some of us can’t wait for them to leave. Here’s what to know about their expected departure. Cicada noise can ‘overwhelm’ people with sensory issues.
Some cicadas produce sounds louder than 106 dB (SPL), among the loudest of all insect-produced sounds. [2] They modulate their noise by positioning their abdomens toward or away from the substrate.

Trillions of evolution’s bizarro wonders, red-eyed periodical cicadas that have pumps in their heads and jet-like muscles in their rears, are about to emerge in numbers not seen in decades and ...
