• diatomes and increases their resistance to mechanical damage. The thin hind wings of diving beetles (Dytiscidae) are fragile and protected by their elytra (leathery forewings). In the resting beetle, the hind wings are folded over the abdomen; in flight, they are unfolded in order to provide aerodynamic

When they see light, they fly to the light source directly from the water. Their hind

• , the hydraulic mechanism in the veins of hind wings of diving beetles (C. japonicus) was investigated, and the unfolding process, including blood flow and pressure changes, was simulated. The study of the hydraulic mechanism in the folding and unfolding process will be provide insights for the design

• . 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
