Why mosquito eggs float

This hand-coloured scanning electron micrograph was the favourite of the jury in the section "Best Scientific Image". The image shows the surface of a mosquito egg (from Culex pipiens), which generates a water repellent network by connecting microscopically small structures to trap a thin layer of air. The vitally important structures avoid immersion and enable the egg to float and aggregate with neighbouring eggs.
