Scientists have discovered that 100 million years ago, the long-mouthed monster, or the mosquito’s ancient “weird relatives”

Reporters from the Chinese Academy of Sciences Nanjing Institute of Geology and Paleontology was informed that by China, Russia, France, the United States, the four countries of paleontologists composed of the research team, the latest in about 100 million years ago in the Cretaceous Myanmar amber found a group of ancient insects related to mosquitoes. These insects are similar in body shape and food to mosquitoes, but they have an “extra-long mouth” that is more than half the length of the body, which is called the “weird relative” of mosquitoes in ancient times.

The findings were published March 5 in the journal Science Advances.

Wang Bo, a researcher at the Nangu Institute of the Chinese Academy of Sciences who led the study, said the newly discovered ancient insect sits have been named the Burmese scorpion. They are about 7 mm long and look like a magnified version of a mosquito. But mosquitoes have one pair of wings, and the Burmese scorpion has two pairs. Another difference is that mosquitoes tend to have shorter mouths, while Burmese scorpions have “extra-long mouths” of up to 3 to 4 mm, which are even more than half the length of their mouths.

The “super-long mouth” of the Burmese scorpion is also a complex internal structure. It consists of two semi-cylindrical coats on the outside and a long tongue in the middle. As soon as the mouth opens, it is like three long spikes protruding together, forming a shape similar to the Trident. And when the tip pierces the barrier and gets the food smoothly, the outer two coats close to form a closed “straw” that follows the straw into the body of the Burmese scorpion.

“Animal forms are closely related to their living environment. Mosquitoes’ mouths and wings are now significantly different from those of the Burmese scorpions 100 million years ago, which may well indicate a significant change in the external environment, such as the plants on which they depend for food. Based on this, we can restore the retweet to get more valuable information about the ancient environment. Wang Bo said.
