densely covers both leaf surfaces, contributes to the plant's adaptation to severe environmental conditions in Antarctica by increasing its resistance to cold temperatures, icing, harmful UV radiation, and dehydration.
In the paper “Micro-structures, nanomechanical properties and flightperformance of
three beetles with different folding ratios”, Sun et al. [8] use modern, high-precision instruments to uncover the relationship between wing morphology and flightperformance of three species of beetles. They use a high-speed camera to track flapping frequency, quantify the surface geometry of the wings

, microstructures and nanomechanical properties of three beetle species with different wing folding ratios living in different environments were investigated. Factors affecting their flightperformance, that is, wind speed, folding ratio, aspect ratio, and flapping frequency, were examined using a wind tunnel. It
was found that the wing folding ratio correlated with the lift force of the beetles. Wind speed, folding ratio, aspect ratio, and flapping frequency had a combined effect on the flightperformance of the beetles. The results will be helpful to design new deployable FWMAVs.
