Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a siphon mouthpart model teaching aid. Background technique [0002] Siphon-type mouthparts, characterized by the degeneration or disappearance of the upper jaw. The outer jaw lobe of the lower jaw is specialized into a curly and extendable beak with a food canal inside, which is suitable for sucking nectar at the bottom of the flower tube. It belongs to most Lepidoptera Unique to insect adults. [0003] The upper lip of the siphonic mouthparts is just a very narrow transverse piece. The mandibular axis and stem nodes are retracted into the head, and the outer mandibular lobes are well developed and embedded left and right to form a beak. The mandibular beard is underdeveloped and the tongue is degenerated. The lower lip degenerates into small triangular pieces, but the lower lip must be developed. [0004] When this kind of insect feeds, the beak is stretched by muscle contracti...
