Insect catching net with aquatic insects capable of being easily taken out

Abstract

The invention discloses an insect catching net with insects capable of being easily taken out. The insect catching net comprises a net bag, a net ring and a net handle, wherein the net bag is an integral conical bag body, through which the net ring passes; one end of the net ring is in an opened structure; and the net handle is configured to be an expansion joint structure. The insect catching net with insects capable of being easily taken out is characterized in that the outer wall of the lower part of the net bag is provided with a binding rope; an insect fetching port is formed in the bottom of the net bag; the insect fetching port is provided with a round pipe with the lower part equipped with an external thread; the round pipe is cooperatively linked with a bottom cover with internal threads; a plurality of small through holes are evenly distributed on the bottom cover along an axial direction; the diameter of the small through hole is less than 2 mm; when the net is swept, the lower part of the net bag is bound by the binding rope; and after the sweeping, the binding rope is untied and insects can be easily taken out of the insect fetching port. Aquatic insects can be easily taken out of the net bag, so aquatic insect collection efficiency can be improved and aquatic insect population analysis statistic accuracy can be ensured.

Description

technical field [0001] The invention relates to the technical field of insect catchers, in particular to an insect catcher net for taking out aquatic insects. Background technique [0002] Collecting aquatic insects in the wild is inseparable from insect nets. The insect net includes a net bag, a net ring and a net handle. The net bag is an integrated conical bag body pierced on the net ring. One end of the net ring is an open structure, and the net handle is set as a telescopic joint structure. Because this kind of insect net has a closed structure at the end far away from the net ring, after aquatic insects enter the net bag, they need to be taken out from the opening at one end of the net ring, which is very easy to escape. In addition to affecting the collection efficiency of aquatic insects, it also Seriously, it will affect the results of statistical analysis of aquatic insect populations. Contents of the invention [0003] The problem to be solved by the present i...
