I have been an admirer, and student of, nature all my life - well for at least as long as I can remember. And my finest teacher was 'baba', my grandmother. We had long walks in her large garden, around the neighor's pond, in the woods near our house and down by the river during my childhood in Slovakia. Nature was our classroom and the plants, animals, anphibians and insects were our subjects. But she never told me about a bug, the lesser water boatman, that was singing with his weenie. A little known fact that she obviously was not aware of.
Tiny water insect makes record-breaking song with his penis
"If you walk by a European river on a summer’s day, you might get to hear the animal kingdom’s champion vocalist. His song sounds like a train of chirps, and from a metre away, it’s as loud as whirring power tools. The din is all the more incredible because it is produced by an insect just two millimetres in length – the lesser water boatman, Micronecta scholtzi
Micronecta means “small swimmer” and it is aptly named. It’s among the smallest of the several hundred species of water boatmen that row across the bottom of ponds and streams with paddle-shaped legs. The males are the ones that sing, and they often do so in large choruses to attract the silent females. These songs are famously loud. Even though the insect lives underwater, you can hear its call from the riverbank, several metres away.
Now, Jérôme Sueur from the Natural History Museum in Paris has measured Micronecta’s song using underwater microphones. He found that it the small swimmer is a record-breaker. On average, it reaches 79 decibels, about the level of a ringing phone or a cocktail party. But at its peak, it reaches 105 decibels – more like a car horn, a power tool or a passing subway train.
There are animals that make far louder calls. The record goes to the sperm whale, which can create clicks of around 236 decibels underwater (equivalent to 170 decibels on land). Other animals, including elephants, hippos and dolphins can produce louder calls than Micronecta.
But pound for pound, there is no competition. All of these animals are very big, and it stands to reason that large objects can produce louder sounds – think about the difference between a concert amp and a set of headphones. The sperm whale, for example, grows up to 16 metres in length and weighs up to 14 tonnes. Micronecta, on the other hand, produces its phenomenal song with a body that’s no bigger than one of these letters. Sueur compared the ratio of call intensity to body size for 227 different animals, from whales to insects, and found that the water boatmen out-sang them all.
How does such a tiny insect make such a loud noise? It’s not clear. It seems to do so by rubbing its ribbed penis against ridges on its belly, playing its genitals like a miniature fiddler. But the “bow” here is just 50 micrometres long, and there are no obvious body parts to amplify the noise. . . . . . "
