Camponotus quadrinotatus is a compact arboreal ant with distinctive markings and lively everyday behavior. Four yellowish spots stand out on the glossy black gaster, while the reddish-brown antennae and mandibles contrast with the lighter sheen of the pronotum and legs. The ants are described as peaceful yet active: workers readily explore the available space, making the colony engaging to watch both during feeding and throughout the day.

Size and coloration

This is a relatively small member of its genus. Workers measure 4–6 mm, queens reach 7.3–8.5 mm, and males measure 5.5–6.5 mm. Despite their compact size, the characteristic pattern remains easy to see, particularly against a light-colored arena. The four pale abdominal spots are the primary identifying feature, accompanied by black, reddish-brown, and light brown tones elsewhere on the body.

Natural range

Camponotus quadrinotatus occurs in East Asia. Records given for the species include Russia, particularly Primorsky and Khabarovsk regions, as well as Japan, North Korea, and China. Its habitats include coniferous, dark-fir, and cedar broadleaf forests.

The species follows a primarily arboreal way of life. In nature, colonies occupy protected cavities in living trees, cracks beneath bark, and sections of old dry wood. This background is relevant to captive housing: the nest should provide a stable microclimate without abrupt shifts in moisture or temperature.

Housing a young colony

A queen with her first workers does not need a large formicarium immediately. A glass test tube or compact incubator is suitable for the initial stage and makes it easier to monitor the family and its access to water. Moving the ants into a larger nest becomes appropriate as worker numbers increase; excessive space at the beginning can make routine observation and maintenance less convenient.

For an established colony, the specified housing format is a fully cast gypsum nest, including versions made from G23 gypsum and fitted into an outer PETG frame. This arrangement distributes moisture through the nesting section while separating the inhabited chambers from the surroundings. Nest capacity should match the current colony size while allowing the setup to be expanded later.

Temperature and moisture

The recommended temperature range for both nest and arena is 23–25 °C. Keep the formicarium away from direct sunlight and drafts, and avoid abrupt temperature changes. Moisture requires measured control: the chambers should not remain completely dry for extended periods, but persistent wetness and excessive watering are also unsuitable.

Key setup points:

• a test tube or small incubator is sufficient for a young family;
• maintain a temperature of 23–25 °C;
• protect the enclosure from direct sun and cold airflow;
• humidify in a controlled manner while checking chamber conditions;
• increase the living area gradually as the colony grows.

Feeding

The diet combines carbohydrate and protein foods. Fresh sugar or honey syrup supplies an energy source. Feeder insects, such as marbled cockroaches or mealworms, provide the protein portion. In nature, these ants consume sweet aphid honeydew and small invertebrates.

Offer syrup and feeder insects in small, fresh portions. Remove uneaten remains from the arena before they foul the enclosure. Protein demand is closely associated with brood development, so portions can be adjusted by observing colony activity and the presence of larvae.

Colony activity

Camponotus quadrinotatus combines a generally calm disposition with noticeable daily movement. Exploration, food transport, and interactions among workers can all be observed in the arena. Avoid disturbing the nest chambers without a practical reason, as consistent conditions are more valuable than frequent inspection.

As the family develops, it will require additional room for workers, brood, and feeding activity. Expansion is best handled in stages, connecting more space after the existing chambers have been occupied. Inspect the outer frame and every connection during routine maintenance, especially after watering or relocation.

Frequently asked questions

Is this species suitable for a beginner?

It can be kept by someone prepared to monitor temperature, nest moisture, and feeding consistently. Beginning with a compact incubator simplifies observation, while an appropriately sized nest can be prepared before the colony outgrows its first container. Little space is required at the early stage, but prolonged microclimate problems should be avoided.

What should the colony eat?

The regular menu consists of sugar or honey syrup together with fresh feeder insects. Carbohydrates support worker activity, while insects provide the protein component used as the colony raises brood.

Can the ants live in an acrylic nest with localized humidification?

The specified arrangement for this species uses a complete gypsum nesting section that can provide a distributed moisture zone. If a PETG outer frame is used, check the fit of all parts, ventilation, and connections. Whatever the material, rely on actual chamber conditions and avoid both prolonged drying and excessive dampness.
