Analysis of Light-mass and High-strength Veins of Hind Wing from Asian Ladybird Beetle

The deployable hind wings of Coleoptera are highly specialized for their flight. The veins of Asian ladybird beetle (Harmonia axyridis) hind wings play a role in its flight. This paper investigates the structural morphology of veins of hind wing in H. axyridis. Additionally, considering the blood in veins, the total mass, and mass distribution of hind wings are studied. The results shown that the variation trend of mass result of the left and right hind wings are almost consistent with the difference of body weight, and the polynomial fit of the mass of left wings (m1), the mass of right wings (m2) and the body mass of H. axyridis (M) are polynomial functions, and the trends of two polynomial functions are similar. The tensile test results are proved that the hind wing of H. axyridis is a high toughness composites due to the veins’ network structure. The light-mass and high-strength vein of deployable hind wings of H. axyridis will be helpful to design biomimetic deployable micro air vehicle (MAV).
