wax lateral


A honeycomb is a mass of hexagonal wax cells built by honey bees in their nests to contain their larvae and stores of honey and pollen.
The axes of honeycomb cells are always quasi-horizontal, and the nonangled rows of honeycomb cells are always horizontally (not vertically) aligned. Thus, each cell has two vertical walls, with “floors” and “ceilings” composed of two angled walls. The cells slope slightly upwards, between 9 and 14 degrees, towards the open ends. The hexagon tiles the plane with minimal surface area. Thus, a hexagonal structure uses the least material to create a lattice of cells within a given volume.
Another explanation is that the shape simply results from the process of individual bees putting cells together: somewhat analogous to the boundary shapes created in a field of soap bubbles. In support of this, he notes that queen cells, which are constructed singly, are irregular and lumpy with no apparent attempt at efficiency.
The closed ends of the honeycomb cells are also an example of geometric efficiency, albeit three-dimensional and little-noticed. The ends are trihedral (i.e., composed of three planes) sections of rhombic dodecahedra, with the dihedral angles of all adjacent surfaces measuring 120°, the angle that minimizes surface area for a given volume. The shape of the cells is such that two opposing honeycomb layers nest into each other, with each facet of the closed ends being shared by opposing cells.

The hive is a system of homeostasis. Homeostasis is the property of a system that regulates its internal environment and tends to maintain a stable, constant condition of properties like temperature or pH. It can be either an open or closed system.
A medium sized nest needs 1200gr wax to be build, and 7,5 kg honey for the energy. Beeswax is composed of more than 300 different chemical components.
The vertical comb construction is parallel to the earth magnetic field, the bees can construct this way thanks to the gravity receptors (organs) that are situated in all their legs and body joints.

The bees’ body is the basic template for the construction of a wax cell. From a cylindrical form the cells become hexagonal under the tension of the regurlarly constructed comb and heated by the bees’ bodyheath (cfr. soap bubbles joining together). The wax wall of a cell is 0,07mm. The antennae of the bees measure the cells’ thickness.

The comb + wax is an integral and inseparable part of the colony as superorganism.
The comb is =>
Living space
Food storage
A skeleton
A sensory organ
A nervous system
A memory stare
An immune system

Functions of the comb =>
Telephone system
Information storage
Colony specific identity
Defense against pathogens
Nursery (center)
Storage & production ⇒ periphery
The nectar/honey is mixed with antibacterial and antifungal peptides and enzymes, before storage in the cells


Bees were very important in the daily life of ancient Egypt. The bee was an insignia of kingship associated particularly with Lower Egypt, where there may even have been a Bee King in pre-dynastic times. The bee was considered sacred by early Egyptians and often regarded as a symbol of resurrection. In Egyptian mythology the Sun God Ra created the honey bee from his tears. The bee, representing the word bit – meaning bee or honey in hieroglyphics, was used as a prefix to the throne name of Egyptian rulers. Bee stood for He of the Bee or King of Lower Egypt.


Diaper is the name given to a textile fabric, formerly of a rich and costly nature with embroidered ornament, but now of linen or cotton, with a simple woven pattern; and particularly restricted to small napkins. In architecture, the term “diaper” is given to any small pattern of a conventional nature repeated continuously and uniformly over a surface; the designs may be purely geometrical, or based on floral forms, and in early examples were regulated by the process of their textile origin. Subsequently, similar patterns were employed in the middle ages for the surface decoration of stone, as in Westminster Abbey and Bayeux cathedral in the spandrils of the arcades of the choir and nave; also in mural painting, stained glass, incised brasses, encaustic tiles, &c. Probably in most cases the pattern was copied, so far as the general design is concerned, from the tissues and stuffs of Byzantine manufacture, which came over to Europe and were highly prized as ecclesiastical vestments.



name: the Bee Laboratory, project, year start: 2009, year end: ongoing, techniques: honeybee colonies, urban gardens, observation technology: sensors, contact microphones, webcams, streaming on open city network

The Bee Laboratory project monitors the behaviour of honeybees in urban surroundings.
 Beekeepers, scientists and artists examine the bee colonies in our rooftop gardens, our open air laboratories. We study the distributed intelligence of the honeybees : their behaviour, ecology and sociobiology. We monitor the bees and beehives with all kinds of eco-technology and we study the colony as a community. We research the interaction between the different colonies as well as the colonies’ behaviour and development in relation to the urban environment.

honeybee monitoring, 2009-ongoing

The monitoring project offers the opportunity to study the bee colonies as bio-indicators. Bio-indicators reflect the health of the ecosystem, they can tell us about the cumulative effects of different pollutants. A bee population functions and evolves very much in accordance to the human activities we are developing around them: gardening and urban agriculture. The production of honey is different related to the flowers we grow, the plants we like, the garbage or pollution we produce.
In our experimental set-ups we work with different kinds of sustainable beehives, and we also build our own observation hives. These hives are augmented with sensors and sensory processing algorithms that analyse the quality of pollen and propolis as well as the behavior of the bees in order to monitor the state of the ecology in the surrounding areas. The ‘Intelligent Beehives’ are distributed in a European network and the data are available online.

The initial setup is located in 2 rooftop gardens in the center of Brussels, at about half a kilometer distance from each other. I installed several beehives in both of the gardens. The bees bridge the spatial distance by foraging in overlapping territories. Since each colony will be active in a radius of 3 kilometers from their hive, the respective trajectories and individual territories will be overlapping and a new space of encounter can be defined. A new perception of neighborhood can be realized through the ‘eye of the bees’.
Observing and monitoring the activities of the hives coupled with ongoing documentation of each individual hive as well as the interaction between the different colonies will be performed. Information can be obtained from bee hives through visually observing, by listening or smelling. Changes of the hives can be monitored in terms of weight, size or outside/inside temperature of the habitation/colony and via the honey amount or quality. This data has abundant environmental information value, but can also be used and made available in a more indirect/symbolic way, as in artworks.

mission statement of the Bee-lab

As artists and beekeepers we study since several years the tight interaction between city honeybees and urban ecosystems.
Our preoccupations with bees come partly from a fascination with these amazing insects: the way their bodies look and function, they way they organize their complex societies, and the way they explore their environment.

But we have also another motivation. In many industrialised nations, bee colonies are now threatened. There are many causes – amongst them pesticides and parasites – but the compromised state of the foraging areas for bees is just as worrisome. So we also work towards an improvement of the environment of bees with the creation of urban gardens and guerilla planting. Moreover, because bees reflect the health of their surrounding ecosystem and the cumulative effects of different pollutants, we use them as bio-indicators to make citizens aware of the increasingly negative effects of our life styles and methods of industrial production.

For many years we have been creating experimental set-ups -together with engineers and scientists- using sustainable beehives that have been augmented with sensors and sensory processing algorithms to analyse the state of the colony, the quality of pollen and propolis and the behavior of the bees. These ‘Intelligent Beehives’ are progressively linked in a European-wide network and the data is being made available online.
More specifically, we have set out several urban test fields in the Brussels’ Canal Zone. This area features diverse activities: from community gardening and urban agriculture to accidental nature, interspersed between industrial buildings, office zones and living areas. Our test sites are connected by the flight routes and foraging activities of the bees. They create a green corridor in the city.

The Bee Laboratory & UrbanBeeResearch should be seen as an open framework. It is a long-term project on the edge of art, science and technology. The project is a collaboration between the artists, designers and engineers from okno.be, annemariemaes.net, the computer scientists ofthe VUB – artificial intelligence laboratory (Prof. Bart de Boer, Free University Brussels) and the Sony Computer Research Laboratory Paris – sustainability group (Ing.Dr. Peter Hanappe).
