The three sexual intertwining stages, “penetration”, “ejaculation”, and “sperm storage” are studied from a biomechanical point of view with a special focus on elongated reproductive organs in leaf beetles. The aim of the study is to unveil how structural variations affect its functionality, thereby we can understand how diversity is produced in nature.
For this purpose different techniques are applied for this beetles by means of inter-disciplinary collaborations: i.e. morphology (with Dr. J. Michels, E. Appel, and Prof. S.N. Gorb), material properties (with Dr. A. Kovalev, Dr. C. Schaber, S. Ito, T. Gödel, and Prof. S.N. Gorb), computer simulations (with Prof. A. Filippov, Dr. H. Rajabi and Prof. S.N. Gorb), and female structural experiments based on 3D printing (with H. Tramsen, S. Gürke, and Prof. S.N.Gorb).
