Evidence that no liquid equilibrium process is involved in the comb building of honey bees (Apis Mellifera) [PDF]

open access: yes, 2017
According to Pirk et al. (2004), honeybees first build free standing cylindrical cells which are then transformed to hexagonal cross-section by wax-flow in a kind of self-organization. We show that there is no self-organization of the wax.
