The lake is basic. The wet diving that lives there is not.

A salt lake swallowed a fly. I know why it swallowed the flies, and it was safe to say that neither the lake nor the flies would die early.

Lake mono, California, is three times larger than the Pacific Ocean and is very basic. Chemically, that’s it. It’s the opposite of the pH of the acid. The lake is full of alkaline alkaloids, which make water soap.

Even people who wash their clothes in the water use a built-in foam to remove dust and oil from their clothes without using soap. The 76-million-year-old lake’s bizarre chemical nature is so hostile that no fish swims under the water, and algae blooms below.

In this fish-free gap in the food web, the base is flying high. The smooth surface of the sea hides rich food, but there is no predator. So, this alkaline fly evolved in a very surprising Angle, hovered in the drink, and then came out like the California desert.

An alkaline fly dives under water and carries a silver pocket around it.

In the “proceedings of the national academy of sciences”, “in an article published at the California institute of technology researchers find out flies is how to handle this trick, because so many monsters cannot cope with the mono lake high alkaline water.

They found that, like other flies, alkali has a small capillary structure and a coating that causes water to slip from the back. But unlike other flies (including flies and flies), these insects have more “hair” and more water-resistant coatings. This combination means that flies can trap a small piece of air bubbles around them while they are swaying underwater.

Bubbles help maintain the energy that flies consume through intense surface tension. Insects must exert 18 times their weight to enter the water, but bubbles can help them float back to the surface.

Biologists, author Michael Dickinson said in a press release: “is not a Mono Lake fly has developed a kind of novel and unique way of keep hydrophobic, but expanded most insects using a conventional tool.” “This is a killer show, underwater nothing can eat, and you have all the food you want, you may only need to dive into the dry earth the most difficult of the water is ok, so enjoy a very unique life history, this small evolution of the physical and chemical changes of how to make the animals to occupy a new niche, this is amazing.

Flies may have been made underwater, but above the surface, they are the food of migratory birds that are surging to the mono lake, and their lakeside larvae are an important source of food for the local people.

Flies face greater human threat. From 1941 to 1982, the lake became more salty as fresh water poured into Los Angeles. The increased saltiness does not seem to affect the fly’s ability to move in water, but other studies have shown that chemical changes may affect larvae.

Fortunately, the increased salinity is being alleviated through conservation efforts and rainfall in California. But that’s not all. In their study, the authors noted that a layer of sunscreen had fallen into the lake from the skin and wondered what the oil would do to the fly. The results of the lab tests, they wrote, were “catastrophic”, trapping flies in the water and eventually drowning them. Fish oil has a similar effect.

So if you’re looking for a sunscreen in lake Mono, consider the fly before dipping your body into the water. Soaking wet may be fine, but if flies can’t stay dry, they’ll die.
