The White mini module is a compact two-chamber formicarium intended for the temporary housing of an ant queen or a young colony. Its small body combines living chambers, a separate micro-arena, and an automatic hydration system, allowing the keeper to observe the ants, provide food, and manage moisture in one unit. It is designed for the early stage of colony development, when a full-sized nest is not yet required but routine care inside a glass test tube has become inconvenient.

Two distinct chambers

The living area is divided into two chambers with different conditions. A 10 mm layer of G23 gypsum occupies only one chamber, while the second chamber contains no gypsum. This arrangement creates a hydrated area and a dry area, allowing the ants to move between them and select a suitable place for brood, resting, or stored food.

Partial hydration can be useful for species that prefer less humid conditions, including steppe harvester ants of the genus Messor. Their seed stores can remain separated from the hydrated gypsum section. The actual moisture level should always be adjusted to the requirements of the species, the size of the colony, and the observed condition of the nest.

Automatic hydration

The automatic hydration system supplies water to the gypsum section. The porous insert distributes moisture gradually within that part of the module instead of wetting the entire living space. The chamber without gypsum consequently remains drier and provides a separate microclimate.

The system makes routine hydration easier, but it still requires supervision. Continually adding too much water may cause mould to develop even on gypsum. The chambers, food remains, and hydration level should therefore be inspected regularly, and standing water or persistent overhydration should be avoided.

Feeding on the micro-arena

An integrated micro-arena provides a feeding and servicing area outside the residential chambers. Suitable food can be placed there without opening the nest itself during every feeding session. This reduces unnecessary disturbance around the queen and workers and also makes leftover food easier to remove.

In a narrow test-tube incubator, feeding and maintenance take place close to the queen and brood. Damp cotton may become soiled over time, while condensation on the glass needs careful monitoring. In this module, the nesting, hydration, and feeding areas are structurally separated, giving the keeper clearer access to each functional zone.

Body and fittings

The transparent components are made from 3 mm acrylic, providing a clear view of both chambers without dismantling the unit. The white structural parts are made from impact-resistant PETG. The layered body is held together with metal fasteners, while nylon components are used in the arena area.

The lid is equipped with close-fitting locking slides. They keep it in position during cleaning, carrying, or an accidental inversion of the module. All slides, joints, and possible exit points should nevertheless be checked before the formicarium is moved or prepared for transportation.

Dimensions and specification

Key construction details:

• overall size — 50×180 mm;
• clearance above the gypsum — 15 mm;
• height in the chamber without gypsum — 25 mm;
• G23 gypsum thickness — 10 mm;
• partial gypsum layout — one chamber with gypsum and one without it;
• transparent components — 3 mm acrylic;
• white components — PETG;
• main fasteners — metal;
• arena components — nylon;
• equipment — automatic hydration and locking lid slides.

A compact starter nest

This model is intended as starter housing for a queen or a small developing colony. It offers more clearly separated functional areas than a conventional test tube, but it is not a permanent substitute for a larger formicarium once the colony expands. When the available living space is no longer sufficient, the ants can be transferred to a larger gypsum or partially gypsum ant farm selected for the biology and space requirements of the species.

Questions and answers

Why is only one chamber fitted with gypsum?

The partial insert leaves a separate dry section. The ants can use it independently of the hydrated chamber, including for seeds when food storage is part of the species’ natural behaviour.

Can the colony be fed without opening its living chambers?

Yes. Food can be placed on the integrated micro-arena, so ordinary feeding does not require direct access to the nest. Any uneaten food should be removed in good time.

Does automatic hydration still need to be monitored?

Yes. It simplifies the delivery of water to the gypsum but does not determine the correct volume for every colony. Excessive hydration can encourage mould, so the moisture level must be checked regularly.

What are the lid slides used for?

They hold the lid in place and reduce the chance of accidental displacement during maintenance or carrying. Every locking point should be inspected before transportation.
