Opis:: This study presents the structure and functions of flying wings in beetles (Coloptera). Structural analysis and function of multiplanar flexion and the structure of the wings in selected beetles were also carried out. The author developed a method of determination of points, structures and surfaces on the wing in folding and flexing motions. The paper describes the system of veins, foils and folds in the wing. Photographs of the wing in different phases of folding and flexion are presented in the paper. The paper emphasizes practical applications of the method of analysis in bionic mechanisms.

Opis:: This paper presents research and measurements leading to obtaining the Young’s modulus of wing bearing structures of selected insect species. A small testing machine intended for three-point bending and equipped with instruments registering low forces was constructed for the needs of the experiment. The machine was used to perform numerous bending tests of wings of three species of insects (obtained from a breeding farm): Attacus atlas, Vespa crabro, Libellula Depressa at various air-humidity conditions. Values of the force and displacement obtained in the course of the tests were used to calculate Young’s modulus. In order to do so, it was also necessary to obtain the moment of inertia of the wing cross-section. These values were measured on the basis of the images obtained with a SEM microscope. Obtained results were averaged and presented with a breakdown by air-humidity conditions. It was observed that Young’s modulus decreased with an increase of humidity, hence the calculations of the percentage decrease of this mechanical parameter were performed. Obtained results were compared with the observed structure which was also presented under light microscope. It transpired that the construction of a wing does not only influence the mechanical values but also it influences their susceptibility to the changes occurring in the environment. Thereby, differences between Lepidoptera and Hymenoptera insects were indicated also within the aspect discussed in this paper.
