Butterflies are no stranger to everyone. However, with the change of ecosystem, butterfly has become a rare species in our life.
In the past, we could see all kinds of butterflies in the rivers and mountains of our hometown. Now we may be very lucky to see a group of about 10 butterflies.
It also shows that the ecological environment in your hometown is really wonderful. Occasionally we can see one or two butterflies, which shows that the environment can be maintained.
However, the comprehensive scientific report shows that in the past 40 years, 73 insect ecological studies in the world have pointed out that more than 40% of insect species are endangered, and about 1% of them are listed on the endangered list every year. This is our butterfly.
According to researchers from the entomological society, this is equivalent to the “largest extinction phenomenon” since the extinction of dinosaurs. Of course, the reason behind it can be said that everyone knows that habitat destruction has disappeared, pesticides and chemicals used in agricultural development are seriously polluted, and climate change and biological invasion account for the majority.
Therefore, “Butterfly” is close to our life, and is also the most easily extinct or disappeared creature. Scientists have discovered another invisible function of butterflies, according to a report in nature communications.
This was discovered by observing the body structure of butterflies. It is not clear whether the “Butterfly” has experienced “super evolution”. What’s so amazing?
It is reported that there is a strong “hidden structure” on the wings of butterflies, which can absorb 99.94% of the light illuminating them and reflect only a small part.
The proportion of black wings is almost comparable to the darkest black coating made by human beings, that is to say, it almost reaches the effect of “reflective” material under the existing technology of “human beings”, and this proportion is only one fifth of the thickness of their wings.
We can imagine how strong the absorptive capacity of this “hidden structure” Black Wing scale is. This may be a completely “supernatural” evolutionary phenomenon, and it should be a kind of hard to find material.
In addition, researchers at Duke University studied 10 species around the world and found that they are 10 to 100 times darker than charcoal, fresh asphalt and velvet.
This is also the most widely studied Black Butterfly sample so far. Its species are from Central America, South America and Asia. However, biologists don’t know why butterflies carry these extremely powerful black wing “scales” and absorb so much light.
This may be a natural structural pattern of butterflies, which may help them recognize certain signals from their mates or predators. However, biologists don’t have a clear idea. There may be other possibilities.
Biologist Thorne Johansen said that under a microscope, scales on a butterfly’s wings look like sponges or nets, and their ridges and pores are supported by tissue similar to pillars. At first, biologists thought that these pillars might affect the reflectivity of their bodies, but after research, it doesn’t matter.
At the same time, under certain conditions, the super black butterfly will also show honeycomb shaped, rectangular and herringbone shaped holes. Computer simulation also shows that the intensity of reflected light is different under different conditions, so this is the butterfly’s self-regulation ability. Then scientists will further study the substance of black butterfly.
From butterflies, we can find some good theories for future technology development, that is, the black scales carried by butterflies can help us design better solar panels and telescopes. It may even be disguised as an airplane, so it can’t be found at night or on radar. Therefore,
It’s a research result that is worth looking forward to. This is the strange point of biology. Although human beings are advanced in science, there are certain limitations.
If some unique “skills” of biology can play a role in our current scientific and technological products, it may be the “technological revolution” of another world. Now, there may be a “boundary” between human technology and biology, but this “boundary” has not been opened.
