Recently, in the Yangxi Provincial Nature Reserve of Yinjiang Autonomous County, Guizhou Province, the first national second-level protected animal was found - the Yangcai Arm Golden Turtle. According to relevant information, this precious insect was declared extinct as early as 1982. However, on September 2, 2004, it "re-emerged from the jianghu" and was found by the Jiangxi Provincial Field Expedition team in the Guanshan Nature Reserve, and an entire ethnic group was discovered.
Since then, the Yangcai Arm Golden Turtle has sprung up like mushrooms. It will be discovered almost every few years, this time in Guizhou.
There are many species of armed golden turtles in the world, from the Himalayas in the west to Japan in the east. However, the Yangcai Arm Golden Turtle is a real-life Unique Chinese Arm Golden Turtle. Therefore, they, which were once judged to be extinct, have been rediscovered, which is of great significance. At present, their level of protection is national level II.
There are not many research reports on insects of the genus Golden Turtle at home and abroad. So far, only 10 species have been reported worldwide, and 7 species have been recorded in China, namely: Yangcai Arm Golden Turtle, Fujian Long-arm Golden Turtle, Taiwan Long-arm Golden Turtle, Indian Long-arm Golden Turtle, Terunuma Long-arm Golden Turtle and Vietnamese Arm Golden Turtle, Gecai Arm Golden Turtle, and Golden Turtle.
It is estimated that many friends will confuse it with ordinary scarab beetles, in fact, the gap between the two is very obvious.

The Yangcai-armed Golden Turtle is a large beetle, and eyewitness records around the world often describe it as being noticed because of its large size. The body length of the Yangcai Arm Golden Turtle varies from 4-7 cm and the width is 2.4-3.2 cm. The scarab beetle is only 2 centimeters long, and the maximum death is only 2.5 centimeters.
The body color of the Yangcai Arm Golden Turtle is dark green but has a beautiful metallic luster, accompanied by some evenly distributed yellow spots, the elytra are close to black-brown, the forebreast is much wider than the back plate, the characteristics of the back plate are similar to the scarab beetle, the middle is concave, but the back plate of the Yangcai Arm Golden Turtle will be more square. The color of the scarab beetle will be more vivid, mostly bright green. If you compare them together, you will find that the color of the Yang color arm golden turtle is richer, but the color is more restrained.

Males will have forefoots longer than their body lengths, while females will be significantly shorter. This pair of forefeets is where the name of the armed golden turtle comes from, and it is also a significant difference between them and other coleoptera orders. Although the characteristics of various armed golden turtles are similar, it is actually very easy to distinguish by identifying color and luster.
They prefer well-lit oak forest areas, preferably in a rainforest environment with a tropical subtropical climate at an altitude of about 993 m. Therefore, our southern region is their main distribution area, of which fujian has the largest number of Yangcai arm golden turtles.
The ubiquitous bugs may seem annoying and meaningless, but why is human research on insects still deepening?
Without insects, the numbers of birds, reptiles, amphibians, fish and mammals would be drastically reduced, as insects are an important source of food. Those of us who depend on animals for food are also affected. They are food, decomposers, pollinators, and important parts of the workings of nature, without which nature would naturally perish.
However, not everything about insects is worth celebrating, and they can also carry disease. Mosquitoes are known as the most dangerous animals in the world because they can carry diseases such as malaria, West Nile virus and dengue fever. Pests eat many crops, causing problems for crop growth and farmers. In China, because of the research of scientists at the end of the last century, the harm of locusts has been very small, but in some parts of the world, locusts can even directly lead to food shortages.
Both the quality of insects makes them important animals to be studied. Research on fruit flies has given us an idea of which genes are involved in many human diseases. They can also help us understand human health in other ways; insects can also be indicator organisms, help us understand whether water sources are healthy, and so on.
There are 2 million species of organisms in the world, half of which are insects. Insects are everywhere, and no matter what language you speak, they will touch you. We must always remember that many beneficial insects do far more good than any bad deeds caused by a few pests.
