• flapping insects with high aspect-ratio wings. The authors then relate the aerodynamic performance of the three species studied to the behavioural ecology requirements of their niches to generate exciting avenues of bioinspiration for flapping micro-air-vehicles. Bargel et al. [9] discuss in their review

• 43210-1142, USA 10.3762/bjnano.9.75 Abstract The hindwings of beetles are folded under the elytra when they are at rest but are extended during flight, which can provide bioinspiration for the design of deployable micro air vehicles (MAVs). Beetle hindwings must be able to be both securely locked under

Keywords: anti-wetting; folding process; interlocking mechanism; micro air vehicles; microtrichia; Introduction Insect wings have many properties, such as lightness, thinness, high flexibility and high load capacity

• . The blood flow and pressure changes are discussed. The driving mechanism for hydraulic control of the folding and unfolding actions of beetle hind wings is put forward. This can assist the design of new deployable micro air vehicles and bioinspired deployable systems. Keywords: bioinspiration; diving
