The world's first muscilla amber has been found

recently, a team of professors from the Agricultural University of China, in collaboration with Wang Bo of the Nanjing Institute of Geology and Paleontology of the Chinese Academy of Sciences, published a research paper online entitled "Early evolution of Nemopteridae illuminated with the first and oldest thread-winged lacewing in Cretaceous amber."
Nemopteridae insect belongs to myrmeleontoidae, the general department of the vein fin Neuroptera ant colony, and is a highly special group of vein fins. The section is very rare, with a total of 142 species, belonging to Nemopterinae and Crocinae, widely distributed in the world's major animal geographical areas except the New North Region, whose species diversity is particularly abundant in South Africa. The form and biological learning of the cytobacteria are extremely special, the disease-forming mouth device is extended in the form of a "duck mouth", with the habit of visiting flowers;
is part of the Ant-Man Division, which includes Nymphidae, Myrmeleontidae, Ascalaphidae, and two extinct † Babinskaisidae and † Rafaelianidae. However, the systematic status of the branch in the general branch of the ants has not yet been definitively determined, some morphological studies show that the department and the branch including the fine branch, the antry branch, and the butterfly horn branch are sister groups, while the molecular data-based pulse fin system development analysis results show that the branch and the antry branch and the butterfly horn branch are sister groups to each other.
time estimates based on molecular data suggest that the first origin of the python was in the Mesothean Period. The oldest fossil record of moths is in early Cretaceous Brazil. The fossil record of the branch is very rare, the Mesocentr is known to belong to 3 genus 5 species, one genus belongs to the extinct yako†Roeslerianinae, the rest of the genus subseters are undetermined; The fossil record of the line-up yako was not seen before this study.

The study, by classifying a large number of fossil specimens of vein fins in Cretaceous Burmese amber, found a beautifully preserved specimen of male python, the Chae cretaceous cretaceous gen. et sp. nov. (Figure 1-2). The discovery represents the first larvae found in amber and the first fossil record of lineworms.
The new genus differs from the other genus of the linen subsoil in that its front wing RP-MA and R have a fork point near-wing base 1/3, the front wing RP branch is mostly forked and slightly bent back, and the male has a long finger-shaped plate (Figure 2). In addition, based on morphological characteristics, this paper reconstructs the development of the inter-genus system (Figure 1A), discusses the new genus from the aspects of system status, living habits, pollination behavior, etc., and demonstrates the hypothesis of the origin of gonwana of the line-line yako from the aspect of biometrics. The results provide important scientific evidence for the early morphological evolution, biological learning and historical biometrics of the group.
