Clown Isopod (Armadillidium klugii) (Dubrovnik)
Armadillidium klugii
The 'Dubrovnik' Clown Isopod (Armadillidium klugii) is a highly ornamental European isopod. It features a bright aposematic color pattern with rows of white and yellow spots bordered with red, mimicking the Mediterranean black widow.

Artbeschreibung
Geographical Origin and Habitat: Native to the dry, rocky, and sun-exposed coastal areas of Dalmatia and the southern Balkan Peninsula (Croatia and Montenegro). They inhabit typical Mediterranean scrublands, old limestone dry-stone walls, and coastal forest margins, taking refuge in deep rock crevices to seek shelter and ventilation.
Taxonomy and Genetics: A popular isopod species known for its defensive behavior of rolling into a perfect sphere (conglobation). The 'Dubrovnik' morph features a slate-gray or lead-black body (up to 18 mm) with a distinctive bright red or orange skirt (pleurites) on the edges. The back is decorated with neat, geometric rows of canary-yellow and white spots, which resemble a clown pattern.
Behavior and Habits: Active and relatively bold compared to other isopod species. They frequently explore their enclosure in the open. Their striking pattern is a form of Batesian mimicry, evolving to resemble the venomous Mediterranean Black Widow spider (Latrodectus tredecimguttatus) to deter predators like birds and lizards.
Morphology: Males and females are visually similar, though females are often slightly larger, wider, and carry eggs or young in a specialized pouch (marsupium) on their underside during reproduction.
Pflege, Zucht und Mitbewohner
Terrarium Setup: Requires a well-ventilated enclosure (minimum 10 liters). Substrate should consist of a 5 cm deep organic soil mix enriched with decaying hardwood, oak leaf litter, and a calcium source like cuttlebone or limestone. Provide plenty of flat cork bark pieces and dry wood for shelter.
Lighting and Heating: Prefers a warm Mediterranean climate. Maintain temperatures between 23 and 26°C. They can tolerate minor nighttime temperature drops, but prolonged cold below 15°C will slow down their metabolism and reproductive cycle.
Humidity and Hydration: they are highly sensitive to high humidity and stagnant air. Maintain a strict moisture gradient: keep 2/3 of the enclosure completely dry and dusty, and only 1/3 damp by moistening a corner with sphagnum moss. Ensure excellent ventilation.
Feeding and Supplementation: Their main diet consists of their organic substrate (decaying leaves and wood). Supplement their diet with carrots, sweet potato, spirulina flakes, and dried gammarus shrimp to support coloration and shell health. Remove uneaten fresh food within 24 hours to prevent mold and pests.
Compatibility: Peaceful, gregarious detritivores. They can be housed in large colonies of their own species or with other peaceful isopods. Avoid housing them with aggressive predators or keeping them in overly humid setups with tropical species.
Health and Common Diseases: The primary cause of death in captivity is excessive humidity, leading to fatal mold infections or suffocation. Always maintain the dry-zone gradient and avoid over-misting. Structural deformities or failed molts occur if there is a lack of calcium in the substrate.

Profil der terrestrischen Wirbellosen
- Diät
- Detritivore
- Clown isopods are vigorous detritivores that feed extensively on decomposing botanical matter. A thick layer of decaying hardwood leaves and rotting white wood should form the basis of their diet in captivity. They eagerly accept supplemental foods like freeze-dried shrimp, vegetable slices, and specialized isopod diets to ensure robust health. A constant source of calcium, such as cuttlebone, is vital for them to properly build and maintain their exoskeletons.

- 2.1 cm
- Lebensstil/Mikrohabitat
- Terrestrial
- They are terrestrial detritivores that inhabit the forest floor. They need a well-ventilated enclosure with a clear gradient, preferring slightly drier overall conditions than some other Armadillidium species while still needing a moist retreat.
- Aktivitätszyklus
- Nocturnal
- As with many isopods, they are primarily nocturnal and crepuscular. They prefer to stay hidden under leaf litter and cork bark during the daytime to retain moisture, emerging at night to feed.
- Sozialität
- Gregarious
- This specific morph from Dubrovnik is slightly less shy than other terrestrial isopods but still favors life hidden beneath bark or leaf litter. When threatened, they employ a defense mechanism called conglobation, rolling themselves into a perfect, heavily armored sphere. They are moderately active explorers in their enclosures, often seen grazing in small, loose groups on decaying matter.
- Reproduktion
- Marsupial
- They reproduce readily when kept in optimal conditions with a stable balance of humidity and ventilation. Females develop a visible marsupium, or brood pouch, on their undersides where fertilized eggs are safely incubated. The eggs hatch into miniature, pale versions of the adults called mancas, which will undergo several molts before developing their signature vibrant coloration.
- Giftig
- No
- Handhabungstoleranz
- Tolerant
- Docile and harmless. When disturbed, they will typically roll up into a ball, showcasing their bright, clown-like warning coloration which mimics venomous spiders in the wild.
- Brumation
- No brumation is required. Keeping them at consistent room temperatures (70-80°F) year-round will promote steady activity and breeding.
- Häutung
- Periodic
- They molt in two stages, characteristic of isopods. They require a calcium source, such as cuttlebone or limestone, and a dedicated moist zone in the enclosure to prevent molting issues and desiccation.
