Recently, the General Station of Forest and Grassland Disease and Pest Control of the State Forestry and Grassland Administration, the Guizhou Academy of Forestry sciences and the Guizhou Leigongshan National Nature Reserve Management Bureau, when conducting the investigation of the parasitic natural enemy resources of pests in Leigong Mountain, discovered a peculiar insect - the chest bearded wasp, which set a new record for Chinese insects.

According to reports, at that time, when investigators caught some insects at the foot of Lei Gong Mountain to identify, they found this strange insect. According to Sun Shuping, a professor-level senior engineer at the Forest and Grassland Disease and Pest Control Station of the State Forestry and Grassland Administration, the insect is a new record in China - Megastylus (Dicolus) pectoralis.
The pectoral bearded wasp belongs to the Hymenoptera family Ichneumonidae, orthocentrinae, megastylus Schiodte, a new record species in China. Previously, only three species of insects in the genus Daisuke had been recorded in China: the yellow-bellied Giant Wasp (M. flaviventris Sheng Sun), the Spotted Bee (M. maculifacialis Sheng Sun), and the black-breasted Large-bearded Wasp (M. nigrithorax Sheng Sun).

In recent years, some rare wild animals and plants have been continuously discovered in the Lei gong mountain national natural reserve. The discovery of the large-breasted wasp not only adds new members to the insect resources of Guizhou Leigongshan National Nature Reserve, highlights biodiversity, but also enriches the record of China's insect resources, and is also a concentrated embodiment of the remarkable results of the ecological civilization construction of this national nature reserve.
Leigongshan National Nature Reserve is located in the middle of Qiandongnan, spanning the four counties of Leishan, Taijiang, Jianhe and Rongjiang, and is the watershed of the Yangtze River system and the Pearl River system, with a total area of 47,300 hectares. Because it has not been invaded by quaternary glaciers, it has become a refuge for many ancient relict organisms, containing rich biological resources, which is not only one of the areas with better vegetation preservation in Guizhou Province, but also an important area with rich subtropical forest plant resources and rare animal and plant resources in Central China.
Among them, wildlife resources are quite abundant, especially reptile species, accounting for 52.8% of the total number of reptile species in Guizhou. There are more than 20 kinds of first- and second-class protected animals such as leopards, white-necked long-tailed pheasants, giant salamanders, mandarin ducks, macaques, pangolins, and black bears. It is also the model production area of three new species of amphibian caudal spotted salamander, spiny finger toad and Thunder Mountain toad, and one new species of reptile Guizhou small-headed snake (refers to the original specimen origin used to determine the name of the species). Among them, the tail spotted salamander is endemic to Guizhou, only Lei Gong Shan and Fan Jing Shan are distributed, and the Lei Shan toad is endemic to Lei Gong Shan and is only found in Lei Gong Shan.
