Tiny bugs make huge sounds with a surprising organA tiny water boatman is the loudest animal on Earth relative to its body size, a study has revealed. Scientists from France and Scotland recorded the aquatic animal "singing" at up to 99.2 decibels, the equivalent of listening to a loud orchestra play while sitting in the front row. The insect makes the sound by rubbing its penis against its abdomen in a process known as "stridulation".
Micronecta scholtzi are freshwater insects measuring just 2mm that are common across Europe. In a study published in the journal PLoS One, the scientists discovered that the small animals make a mighty sound. The team of biologists and engineering experts recorded the insects using specialist underwater microphones. Dr Windmill explained that the reason the insects don't deafen us is down to the bug's underwater lifestyle.

Although 99% of the sound is lost when transferring from water to air, the songs were still loud enough to be audible to the human ear. The majority of the loudest animals on Earth are also the biggest, with blue whale songs reaching 188 dB and elephants' rumbling calls measuring 117 dB. Although remarkable acoustic signals are made by a range of invertebrates, including the miniature cricket and preying mantis, and by large mammals, none compare to M.
Researchers believe that sexual selection could be the reason why the insects' songs reach such high amplitude. Dr Sueur explained that the competition could have exaggerated the volume of males' songs over time. In many insects, the song volume is limited because predators would hear them, but observations suggest that M. To produce the intense sound, the water boatmen "stridulate" by rubbing a ridge on their penis across the ridged surface of their abdomen.

Without any obvious adaptations to amplify the sound, the question of how the animals physically make such a loud call remains a mystery. We first thought that the sound was coming from larger aquatic species such as a Sigara species [of] lesser water boatmen," said engineering expert Dr James Windmill from the University of Strathclyde, Glasgow. This is a pyrallid moth, Syntonarcha iriastis, that uses highly modified genitalia to produce ultrasonic signals," explained Dr Sueur.
