When ants drink water, do they have to bite it off because of surface tension?

I am a masters student of Engineering specialising in microfluidics.  - / The mouth or jaws of the ant are composed of a rough surface together with very small hairs. This surface is thus hydrophobic at that small scale. The scale influences the surface/volume ratio which causes surface forces to dominate. The jaws, when clamped shut, will most definitely be able to "cut" off a droplet from a bigger drop.
