A vivid formicarium with a carefully organized living area

ANTMART Honeycomb Yellow 220x110, Variant A combines a bright yellow body, transparent viewing panels, and a network of hexagonal chambers. The contrasting design makes it easier to watch workers moving through the nest and observe the colony as it develops. The model measures 220x110 mm, while the Variant A layout uses a partial gypsum humidification system to provide both moister and drier areas within one nest.

Body materials and fasteners

The formicarium is assembled from yellow, white, and transparent 3 mm acrylic together with impact-resistant PETG plastic components. These materials form a rigid layered enclosure designed for routine maintenance and clear observation of the colony.

White nylon fasteners are used instead of steel bolts. Nylon does not rust in a humid environment, making it suitable for an enclosure that contains a water-fed gypsum insert. It also avoids the visible corrosion that may develop on unprotected metal hardware exposed to moisture.

Honeycomb passages and staged expansion

The living area is arranged as a series of honeycomb-shaped chambers. This geometry provides multiple connected spaces in which the ants can distribute brood, workers, and stored food. Passage height reaches up to 21 mm, so the dimensions can also accommodate species with relatively large queens.

Independent dividers separate the nest into three sections. Additional sections can be opened gradually as the colony grows instead of giving a small family access to the entire nest at once. This makes it possible to adjust the occupied area during different stages of colony development.

Partial humidification with G-23 gypsum

A 6 mm slab of high-density G-23 gypsum is installed in the nest. Water travels through its capillary structure, producing a humidity gradient: areas near the humidification chamber become moister, while sections farther inside remain drier. The ants can therefore place eggs, larvae, pupae, and food stores in different parts of the nest according to the available moisture.

The gypsum covers only part of the nesting area. This arrangement is particularly relevant to seed-harvesting Messor ants: humidified chambers can be used for brood, while dry compartments remain available for storing seeds. Dense G-23 gypsum was also selected with the mechanical action of ant mandibles in mind.

Feeding and display arena

The arena is 80 mm high. It provides room for a feeding station and suitable decorative elements while retaining access for feeding and cleaning. Transparent walls allow the keeper to inspect the arena without dismantling the living section.

Its lid consists of two acrylic layers. The layered construction adds rigidity and helps reduce deformation associated with humidity. Mechanical sliding locks press and secure the lid against the enclosure, reducing the likelihood of gaps or accidental opening. All joints and lock positions should still be inspected regularly, particularly before the formicarium is moved.

Suitable ant groups

The combination of dry and humidified chambers is primarily intended for Messor, which require separate areas for brood and seed storage. The passage dimensions and nesting layout also make the model a possible option for Camponotus and Pogonomyrmex. Keepers must still check the temperature, humidity, nest-space, and escape-prevention requirements of the exact species: physical compatibility with the enclosure does not replace species-specific husbandry.

Questions and answers

• Why is Variant A useful for Messor?

Messor collect and store seeds, so they benefit from both humidified brood chambers and dry storage areas. The partial G-23 slab produces different moisture levels inside the same nest. Damp areas are available near the humidification system, while compartments beyond the gypsum section remain drier. Humidity must nevertheless be monitored and adjusted for the particular species and the current condition of the colony.

• What is the purpose of nylon hardware?

The gypsum is supplied with water, creating a humid environment inside the formicarium. White nylon fasteners do not rust under these conditions, unlike ordinary unprotected steel components. This is a practical choice for a layered enclosure, although assembly security also depends on correct tightening, the condition of each component, and regular inspection of the joints.

• How does the double arena lid work?

The lid is made from two acrylic layers and secured by mechanical sliding locks. The layers add stiffness, while the locks keep the lid pressed against the body. This arrangement reduces the chance of gaps and unintended opening. Before introducing ants, the keeper should still inspect the perimeter, test every lock, and confirm that any remaining clearances are appropriate for the selected species.
