Camponotus pseudolendus is a rarely encountered member of the genus Camponotus from the humid, partly shaded forests of southern China. Its appeal lies in a combination of polished dark coloration, pronounced worker polymorphism, and purposeful colony activity. Fast foragers patrol the arena, large soldiers guard access to the nest, and the division of labor becomes especially clear during feeding or defensive responses.

Appearance and size range

The name reflects a close relationship to Camponotus dolendus: the prefix pseudo- means “false.” Despite the resemblance, Camponotus pseudolendus has distinguishing morphological details. Its abdominal hair is less pronounced, giving the chitin a smoother, glossier appearance. The body may look deep matte black or dark brown, while the thorax and legs often carry chestnut or reddish tones.

Recorded sizes vary by caste:

• queen: 13–15 mm;
• workers and soldiers: 7–12 mm.

Polymorphism is a prominent feature of the colony. Heavy, large-headed soldiers use powerful mandibles to defend nest entrances and process protein prey. Smaller, agile foragers continuously explore the available territory, locate food, and recruit other workers. This contrast makes the colony’s internal organization easy to observe.

A humidity gradient, not a uniformly wet nest

In nature, the species is associated with stable humidity. That does not mean every chamber should remain equally damp. Larvae require moderately humid areas, whereas cocoons need completely dry chambers. Creating both conditions within the same nest is the central husbandry task: moisture must remain available without waterlogging the occupied space.

The source recommends partially gypsum-based or traditional gypsum formicaria. Hygroscopic G23 gypsum distributes moisture, while spacious PETG sections provide additional functional areas. This arrangement allows workers to relocate brood and select the microclimate that suits each developmental stage.

The original guidance advises against acrylic nests that rely on nano-sponges for this species. Such systems may fail to maintain the required balance, leaving some chambers too dry while encouraging mold in others. Gypsum still requires supervision; it assists with water distribution but does not remove the need for measured hydration and regular observation.

Temperature and seasonal rhythm

The stated arena temperature is 25–28°C. As a species from southern China, Camponotus pseudolendus does not require severe refrigeration. The source instead describes a mild diapause lasting about two months at a room-temperature range of 20–22°C.

Feeding the colony

The diet has two essential components. Thick sugar or honey syrup supplies carbohydrates for active workers. Animal protein supports the brood and the development of new soldiers. Crushed Turkestan cockroaches and crickets are the specified protein foods.

Feeding also reveals how the castes cooperate. Foragers rapidly locate an insect and mobilize nestmates, after which larger individuals help process it. The species is described as relatively peaceful under routine conditions, but large soldiers respond actively when the nest itself is threatened and can defend it with their strong mandibles.

Preparation checklist

• A formicarium capable of providing both dry and moderately humid chambers.
• A stable arena temperature of 25–28°C.
• A carbohydrate source and suitable feeder insects.
• A controlled hydration routine that avoids standing water.
• Conditions for a mild two-month diapause at 20–22°C.

Frequently asked questions

What is the main husbandry challenge?
The key issue is moisture distribution rather than simply keeping the nest humid. Larvae need moderate moisture, while cocoons should remain in dry chambers. A gypsum system can help establish this gradient, but the keeper must still monitor and adjust hydration.

How defensive is the species?
The ants are described as fairly peaceful during normal activity. When the nest is disturbed, however, major workers defend its entrances with powerful mandibles. On the arena, foragers move confidently and recruit quickly after finding feeder insects.

Does Camponotus pseudolendus require cold wintering?
No refrigeration is specified. The source recommends a light seasonal diapause at 20–22°C for approximately two months rather than a harsh cold period.

Who is this species suited to?
Camponotus pseudolendus suits a keeper who wants a visibly polymorphic, active colony and is prepared to manage a precise humidity gradient. Its interest extends beyond coloration: the smooth dark chitin, chestnut accents, fast scouts, heavy soldiers, and coordinated feeding response provide several distinct aspects to observe.
