Clown Isopod (Armadillidium klugii 'Montenegro')

Armadillidium klugii 'Montenegro'

The Armadillidium klugii 'Montenegro'. Famous all over the world as 'Clown Isopod', it is a striking Mediterranean isopod (0.6-0.7 inches) that enchants with its theatrical livery. It simulates the appearance of poisonous spiders (Latrodectus) with a dark brown back bordered by huge white margins and speckled with three rows of incandescent red or yellow dots. Extremely tolerant to arid climates, it closes into a perfect sphere and devours proteins, dry debris and barks, making it perfect for dry and hot Mediterranean biomes.

Species description

Geographic Origin and Habitat: A taxonomic revision lists examined Armadillidium klugii material from Montenegro, including Lovcen Pass and Kotor. It does not establish captive environmental requirements for the catalogue’s quoted ‘Montenegro’ line.
Taxonomy and Genetics: Schmalfuss (2013) treats Armadillidium klugii Brandt, 1833 as a nominal species of the Armadillidium klugii-group. The source is a morphological taxonomic revision and supplies no genetic result for this entry.
Behaviour and Habits: The cited taxonomic revision provides no species-specific behavioural observation; no behavioural or captive-management claim is inferred here.
Morphology and Sexual Dimorphism: The diagnostic characters give a maximum dimension of 21.0 × 9.3 mm. The most frequent variety is described with grayish-brown dorsal parts, three yellow patches on the pereion-tergites, and yellow epimera and telson; the source also records variation in this coloration.

Life expectancy
No verified data available
Adult size
2.1 cm
The catalog's scalar value is 2.1 cm. The Schmalfuss (2013) — revision of the Armadillidium klugii group source reports a maximum adult measurement of 2.1 cm for this species, recorded as the dataset's reported length dimension. The biological datum refers to the base species Armadillidium klugii, not exclusively to the commercial variety. These figures are not interchangeable: the first is the profile's editorial reference, whereas the second is a published maximum under a specific measurement convention; differences among sources can reflect sex, population, life stage and measuring method.
