(a) Scanning electron microscope (SEM) micrographs (shown at three magnifications) of lotus (Nelumbo nucifera) leaf surface, which consists of microstructure formed by papillose epidermal cells covered with epicuticular wax tubules on the surface, which create nanostructure and (b) image of a water droplet sitting on the lotus leaf (Bhushan et al. 2009). Scale bars, (a)(i) 10 μm, (ii) 2 μm and (iii) 0.4 μm.

4. Optical micrographs of water droplets on Rosa cv.
Optical micrographs of water droplets on Rosa cv. Bairage at (a) 0° and (b) 180° tilt angles. A droplet is still suspended when the petal is turned upside down (Bhushan & Her 2010). Scale bars, (a,b) 500 μm.

7. (a) Schematics of a solid–water–oil interface system.
(a) Schematics of a solid–water–oil interface system. A specimen is first immersed in water, and then an oil droplet is gently deposited using a microsyringe, and the static contact angle is measured. (b) Optical micrographs of droplets at three different phase interfaces on a micropatterned surface (shark-skin replica): (i) without and (ii) with C20F42 (Jung & Bhushan 2009). Scale bar, (b) 0.5 mm.

9. The water-capturing surface of the fused overwings (elytra) of the desert beetle Stenocara sp.
The water-capturing surface of the fused overwings (elytra) of the desert beetle Stenocara sp. (a) Adult female, dorsal view; peaks and valleys are evident on the surface of the elytra and (b) SEM image of the textured surface of the depressed areas (Parker & Lawrence 2001). Scale bars, (a) 10 mm and (b) 10 μm.
