In the beetle world, the vast majority of beetles are cold-phobic, and during the cold winter months they either die or hibernate. In some high-altitude areas, too, the number of beetles is usually small due to the temperature difference caused by altitude. But there is a class of beetles, which are naturally fond of high altitudes and low temperatures, and they have strong jaws, variable tooth shapes, and a pair of ears. This is the genus Lucanus.
Daming deep mountains
There are a large number of species in the genus Deep Mountain Spade, which can be divided into two categories, one is the large deep mountain, the common European deep mountain, the spotted deep mountain, the giant fork deep mountain, the Fury deep mountain are all in this series, due to their large size, their larval feeding habits are partial to decaying wood, like most spade shell species, the larvae feed on decaying wood. Since there are no large numbers of decaying wood in high altitudes, they mostly live at lower elevations.
The other type is small and medium-sized deep mountains, that is, the common Ji Deep Mountain, Lucky Deep Mountain, Sichuan Deep Mountain, and Perry Deep Mountain. This can also be subdivided into two categories, one is the low-altitude small and medium-sized mountains such as Ji Shen Shan and Perry, whose larvae mostly feed on humus soil and also feed on decaying wood. There is also a high-altitude small and medium-sized deep mountain, such as Kashi deep mountain, junya deep mountain, Sichuan deep mountain, etc., their larvae eating habits like fans, it is rumored that some people have dug up larvae under the bamboo roots, there are also people who find larvae under the roots of live shrubs, there are also people who find larvae under rotten tree stumps, about the habits of such larvae, people have different opinions, in Japan, in Taiwan, in Hong Kong there are some beetle lovers breeding high-altitude small and medium-sized deep mountains, and raising adult insects, but in the mainland, but there has been no successful news.
Many successful breeding records, it is not difficult to find that the use of very rotten fermented wood chips feeding, then in the wild these larvae should live in deciduous soil or rotten tree stumps, but compared to the large number of adult insects, the larvae that can be found in decaying tree stumps are less than one-thousandth.
Another problem that plagues us is that in the high-altitude areas where the deep spades live, the soil layer will become frozen in winter, and at such a low temperature, the larvae will completely stop growing and enter a dormant state. Artificial breeding can avoid this stage and give the larvae a longer growth time, but the final result is that the artificial individuals are all small individuals, and the suitable environment does not make the insects grow larger, is the ingredients wrong, or the temperature is not right, or? There are too many problems that plague us, but with global warming and human destruction of the environment, the living conditions of these creatures at high altitudes are precarious, and it is not known whether they will survive until we solve all the mysteries...
