Description

A collection method of snakefly TECHNICAL FIELD

[0001] The present application relates to the technical field of insect collection, in particular to a collection method of snakefly. BACKGROUND

[0002] Snakefly, as the general term of insects in the order Raphidioptera of the class Insecta, exhibits a unique and fascinating biological form. They have a slender body shape, exhibiting an elegant streamlined appearance, which makes them unique in the insect world. Snakefly insects are widely distributed, almost covering all continents except Australia and Antarctica. They usually live in forest environments, feeding on the larvae of other insects, playing an important role in nature as predators, helping to control pest populations, and thus being considered beneficial insects.

[0003] Research on snakefly has so far focused on its taxonomy, geographical distribution, and morphological characteristics, especially on the morphological study of extant species. However, the study of snakefly life habits, such as diet, reproductive behavior, and life history, is relatively limited, mainly due to the relatively small size of snakefly individuals and their habitat in tall trees, making it difficult to collect specimens. Traditional collection methods, such as netting, sweeping, or trapping, can effectively obtain adult samples, but they are not effective for collecting larvae, especially in recording insect emergence times. These factors limit our comprehensive understanding of snakefly ecological habits and affect deeper scientific research on this insect group.

[0004] Through previous collection methods such as netting, sweeping, and trapping, mainly for collecting adult insects, it is difficult to achieve the desired effect of collecting larvae and recording insect emergence times, which affects further research on insects. Therefore, it is of great significance to develop new collection techniques and methods to improve the observation efficiency of snakefly larval stages and emergence process, and to promote the in-depth exploration of the ecological characteristics of this unique insect group.
