A bright formicarium built for close observation

The ANTMART Labyrinth White 220x110 mm, Variant A combines a high-contrast finish, a branching chamber layout, and partial gypsum humidification. White and transparent body panels make workers, the queen, larvae, and egg clusters easier to examine, while the labyrinth configuration provides several functional areas for the colony. The model is intended for gradual occupation and is listed for steppe and woodland ants, including Messor and Formica. The source recommendations also mention Camponotus and Pogonomyrmex.

Construction and materials

The body uses 3 mm white and transparent acrylic together with PETG plastic components. Its overall size is 220x110 mm. Nest passages are up to 21 mm high, providing room for relatively large queens and workers, while the arena has a height of 80 mm. This arrangement offers a clear view of activity in both the residential chambers and the open foraging area.

White inert nylon fasteners are used instead of conventional metal bolts. This is a practical choice in a structure where fittings remain close to moist gypsum: nylon does not rust or release corrosion products into the humidification material. The glossy white background also creates visual contrast and makes it easier to notice brood, stored food, discarded material, or changes on chamber surfaces.

Partial gypsum humidification

A 6 mm slab of G-23 dental gypsum is installed in part of the residential section. Because the slab does not cover the entire nest, it creates a transition between more humid and drier chambers. The ants can distribute brood, the queen, and stored food according to their needs. In colonies of seed-harvesting Messor, the dry section can keep seed stores separated from the more humid brood area.

G-23 has a denser structure than soft construction alabaster and is therefore more resistant to mechanical wear. It should not, however, be treated as indestructible. Its service life depends on the ant species, the humidification routine, and general handling. Water should be added in a controlled manner without sudden flooding, following the actual moisture level and the biological requirements of the colony.

A reinforced arena cover

The 80 mm arena is protected by a cover made from two acrylic layers. The added layer increases rigidity and reduces the likelihood of bending caused by temperature changes or humid vapour. Mechanical sliding locks hold the cover against the body during observation and transport.

This design reduces the chance of gaps developing, but it does not remove the need for routine safety checks. Before moving or servicing the formicarium, inspect the seating of the lid, every lock, joint, ventilation area, and attached module. When the arena is open, handling precautions should reflect the speed, size, and behaviour of the species inside.

Four sections for controlled expansion

Removable partitions divide the labyrinth into four independent sections. A small colony can begin with access to a limited number of chambers. Additional territory can then be opened as the worker population increases. Matching the available volume to colony size helps the ants establish a compact nest and may discourage them from turning surplus chambers into refuse areas.

Construction summary:

• overall dimensions: 220x110 mm;
• 3 mm white and transparent acrylic;
• PETG plastic components;
• partial 6 mm G-23 gypsum slab;
• white inert nylon fasteners;
• four sections with removable partitions;
• passage height up to 21 mm;
• arena height of 80 mm;
• two-layer lid with mechanical sliding locks.

Species compatibility

The partial humidification layout is especially practical for Messor because it combines a moist brood section with drier chambers for seed storage. The stated passage height can accommodate comparatively large queens and workers. Formica, Camponotus, and Pogonomyrmex are also named among the intended ants. Final suitability must still be assessed for the exact species, colony size, moisture requirements, worker dimensions, and its ability to damage construction materials.

Questions and answers

• What is the practical benefit of the white background?

Dark ants, brood, and stored material stand out clearly against a light surface. Refuse and unwanted changes on the gypsum may also be easier to detect. Lighting should nevertheless remain moderate, as constant bright exposure can disturb a colony regardless of the acrylic colour.

• Why is only part of the nest fitted with gypsum?

A partial slab creates a moisture gradient rather than making every chamber equally humid. The ants can choose suitable conditions for brood, the queen, or food reserves.

• What are the removable partitions for?

They allow the available nesting area to expand with the family. A young colony starts in a compact section, and further parts of the labyrinth are opened as its population grows.

• Does the double lid make escape impossible?

The two acrylic layers add rigidity, while the locks reduce the risk of an unsecured edge or gap. Even so, the cover and every connection should be inspected before maintenance or transport.
