The present disclosure relates to an arrangement () for controlling an entrance hole () of a beehive () of a beehive with bees, comprising a closure element () for at least partially closing the entrance hole (). According to the present disclosure, the arrangement () comprises at least one identification unit () arrangeable or arranged on a queen bee (), a reading unit () for reading out the at least one identification unit (), wherein the reading unit () or at least one antenna unit () of the reading unit () is arrangeable or arranged at the entrance hole (), and an actuation unit (), in particular coupled with the reading unit (), for actuating the closure element (). Moreover, the present disclosure relates to a method for controlling an entrance hole () of a beehive ().

A method of making a structure having an optimized sterical shape of a materialcomprises the steps of forming a pre-formof the structure of the material, setting geometric boundary conditions for the materialbeing in a state in which it is able to rearrange under the influence of internal tensions in the volume of the pre-formso that the material rearranges itself into the structure in a self-organized way, and transferring the rearranged materialinto a state in which the rearrangement of the materialis conserved.
