Illustration of the surface structures and bouncing phenomena. a Schematic illustration of water droplet on the termite wing. b Schematic illustration of surface structures of the termite wing. c Schematic illustration of the surface structures mimicking the surface structures of the termite wing. Water droplets (7.6 ± 0.6 μL) were poured from a height of 10 cm onto the surfaces for monitoring the bouncing phenomena. d Optical images of a bouncing droplet on Surf1c+2c. A small droplet remained on the surface (blue arrow). e Optical images of a non-bouncing droplet on Surf1c. f Optical images of a bouncing droplet on Surf2c. Scale bar of expanded image is 1 mm
