Numerous animals have discovered loam’s and mud’s potential as a building material — including humans, who have been using loam for thousands of years. This study exhibition traces the footsteps of master builders, big and small, and presents incredible mud-built nests crafted by wasps and birds, and objects made by loam-building humans. Potter wasps in particular impress with their constructions for their offspring. Ball by ball, these animals build small pots, tubes, or entire nests containing multiple brood cells. But unlike social wasps, these nests do not represent a colony containing hundreds of workers. Each female potter wasp is her own queen and does all the work herself, from nest building to gathering food. Dried by the sun, the mud constructions form a stable home for the wasp larvae. In addition to numerous original natural objects, films, and photographs, the exhibition also features large-scale models created by award-winning taxidermist Detlev Gregorczyk.
