Pallasii Isopod

The Pallasii Isopod is a large woodlouse native to the coastal regions stretching from the Adriatic to the Ionian Sea. It grows to roughly 2.4 cm, making it one of the more substantial isopods in the hobby. The semi-transparent orange form from Corfu Island is especially prized for its striking coloration. Calm and unassuming, these isopods spend their time tucked into soil and leaf litter in classic isopod fashion. Unlike many isopod species that favor high humidity, Pallasii prefers drier conditions, so its care routine differs slightly — but it remains considered beginner-friendly, and once established, colonies tend to grow steadily. It's a quietly captivating species to observe.

7 things to know before welcoming a Pallasii Isopod

  1. 1Prefers Drier Conditions
