Scientists unveil secret to strength in locust wings

The video explains how locusts primarily use their hind wings for flight. The durability of their wings is attributed to a grid-like structure formed by longitudinal and cross veins. Cross veins play a crucial role in inhibiting crack propagation, although increased tension can lead to crack development. Microscopically, longitudinal veins have elliptical cross sections, while cross veins exhibit an emulated pattern, enhancing wing durability by up to 50%.
