The invention relates to a bionic tree for moving habits of small insects, comprising a primary transparent hollow trunk pipe. The bionic tree is characterized in that the upper end part of the primary transparent hollow trunk pipe is provided with an extending splicing through hole; and the extending splicing through hole is spliced with a secondary transparent hollow trunk pipe. The bionic treefor the moving habits of the small insects has the advantages of simple structure and reasonable design, and is favourable for researchers to observe the habits of the small insects, and the model ofthe main branch of an entity plant can be fully simulated.
