And the effect of this is that as the droplets start to form on the bumps, they stay in tight, spherical beads, which means they're much more mobile than they would be if it was just a film of water over the whole beetle's shell.
Acontece que, à medida que as gotículas se começam a formar nos altinhos, formam grânulos esféricos e apertados, que são muito mais móveis do que seriam se fosse só uma camada de água em cima da carapaça do escaravelho.
