Peraccae Isopod

The Peraccae Isopod is a large woodlouse native to southeastern Italy through the Aegean and into Turkey. Its blue-gray body is covered in coarse, raised granules that give it a rugged, almost trilobite-like texture unlike most other isopods. When threatened, it rolls into a tight, complete ball — an endearing defense that never fails to catch the eye. In the wild it gathers in groups beneath bark, and in captivity it proves hardy and breeds readily, making it a popular starting point for anyone new to keeping isopods.

About Peraccae Isopod

A large, hardy woodlouse from southeastern Italy and the Aegean, known for its blue-gray, trilobite-like granulated shell — an easy, beginner-friendly isopod.

7 things to know before welcoming a Peraccae Isopod

1Recreating Its Habitat
In the wild it lives along the warm Mediterranean coast from southern Italy to Turkey, so captive setups should offer moderate humidity with good airflow. Since it naturally shelters under bark and leaf litter, provide plenty of hiding material to mimic that environment.
2Rolls Into a Full Ball
When disturbed, it curls its entire body into a tight ball to protect itself. This is a natural defense that shields its soft underside from predators, so it's best handled gently and not startled unnecessarily.
3A Social, Group-Living Species
In the wild it clusters in groups beneath bark, so it tends to do better kept in numbers rather than alone. In captivity you'll often see individuals gathered together under the same hide.
4Hardy and Beginner-Friendly
This species is naturally tough and tolerates minor fluctuations in its environment, which is why it's considered beginner-friendly to keep. Consistent humidity control and feeding are all it really needs to thrive long-term.
5Easy to Breed
Under stable conditions, this isopod breeds fairly readily in captivity, and colonies often grow without much intervention. If you want to keep breeding going, make sure there's enough space and food to support a growing population.
6Adult Size
Adults reach around 1.7 to 1.8 cm in length, making this a relatively large species of woodlouse. That size also makes its granulated, trilobite-like texture easy to appreciate up close.
7Plan for Its Lifespan
As a general figure for the genus, this isopod tends to live around two to three years. Before bringing one home, it's worth confirming you can keep up the enclosure care and have the space and time for that duration.
