Introduction: Looks like a spider, often on the surface of the water "Ling Bo microstep", what is it a bug?
In the summer, the temperature is high and the rain is heavy.
Sometimes it rains heavily in the southern region, and the rivers and ponds will swell.
Many people will wait until the rain stops at this time, and take the opportunity to go to the ditches, paddy fields and ditches to catch fish, often harvesting a lot.
Have you noticed that there is a kind of insect that resembles a plant, but it can walk freely on the surface of the water and will not sink, it is almost like practicing duan Yu's "Ling Bo Micro Step", which is a martial arts mastery.
So what is this bug called? Is it a beneficial insect or a pest? Let's take a look at it today.
<h1 class="pgc-h-arrow-right" data-track="40" > commonly known as water tanks, scientific name water</h1> tanks
This bug has always been called a water spider in our local area, and some people call it a "water tank". Later, when I grew up, I learned that it was called a water shrew.
The water fly is not a water fly, because the word "黾" is pronounced (mǐn), not a fly.
However, some places also call it water mosquitoes, water horses, or jellyfish, water benches, etc.
Water shrew is a small aquatic insect distributed in the north and south of China, it is an aquatic hemiptera, weeds, large cockroaches, small insects of the genus Water Shrew.
It is mainly active on the still water surface of some ponds and reservoirs, or on the slow flow surface of some streams.
This animal looks very similar to a spider, with a black-brown body, a body length of about 22 mm, and 6 legs, 3 legs on each side.
The front legs are short, and the middle and back legs are long, which is somewhat similar to a rabbit, so it crawls very fast and moves quite quickly. As soon as someone approached, quickly crawled away.
It is simply the reputation of the insect world's "Lingbo microstep".
It doesn't sink on the surface of the water, even if it's a quick crawl. This is because it has a lot of fine high-quality fluff distributed on its legs, and it has a waterproof effect, thus protecting itself from sinking on the water.
<h1 class="pgc-h-arrow-right" data-track="39" > the habits of the water shrew</h1>
Most people see the water bask on the surface of the water, but in fact it can also live on land for a period of time.
The water mole mainly feeds on the bodily fluids of the insects that fall into the water, and also eats the small fish and shrimp that die, as well as some insects.
Although the eyes of the water weed are not sensitive, because the eyes of the water weed family have been degenerated, it has a pair of compound eyes located on both sides, which are very developed, so the vision is very good.
When they find an insect falling into the water, they will crawl over quickly and then use the sensitive organs on their front legs to feel whether the insect is struggling.
Once the food is determined to be dead, the tubular mouth is inserted and its juice is sucked.
As we all know, there are many mosquitoes at some water's edges, and the water mole mainly preys on some mosquitoes that fall into the water, and at the same time preys on the eggs they lay.
In this respect, water shrews are a beneficial insect because they prey on these pests such as mosquitoes.
In addition, water moles also have a certain role in purifying water quality. Many insects that fall into the water body are eaten by the water shrew.
In addition, the water mole also likes to eat a little float on the surface of the water, and many subtle items that fall on the surface of the water.
For example, the carcasses of insects, insects, and insect eggs in the water can become the food of the water shrews, thus playing an effective role in purifying the water quality.
Some people also compare the water shrew to a "water scavenger", which shows that the evaluation of it is very high.
The value of the water surface
Some scientists are very interested in being able to walk freely on the water, and have also conducted in-depth research and understanding of it.
The study found that this is mainly due to the fact that there are many fine villi on the legs of the water mole, which hinders the infiltration of water droplets. Coupled with the fact that the water weasel is very light and small, and its six legs share the weight in balance, this is the reason why it can walk freely on the surface of the water, even in the storm and rapid flow of water will not sink.
It is also because of this property of the water weasel that scientists have also invented the water robot.
<h1 class="pgc-h-arrow-right" data-track="34" > concluding remarks</h1>
It is often found in flocks on the surface of the water, and in the past many wells, ponds and slower-flowing rivers can be seen in the water surface.
But now because of the water quality, many places are difficult to see. In my hometown, it is difficult to see water weasels.
Friends, now you know what it is called, this is a harmless little insect to people and animals, and it is also an inspector of water quality, which has a good role in cleaning water quality.
