Butter Pecan Isopods (Porcellionides pruinosus)
“Butter Pecan” Isopods are a beautifully warm-toned morph of Cubaris murina known for their creamy caramel, tan, and buttery brown coloration. Their soft earthy tones and active nature make them a standout addition to both bioactive enclosures and dedicated isopod collections.
Hardy, adaptable, and relatively easy to care for, Butter Pecan Isopods thrive in tropical and semi-humid environments where they work as an efficient cleanup crew by consuming decaying organic matter, leftover food, shed skin, and waste. Their moderate reproduction rate and attractive coloration make them a favorite among hobbyists looking for both functionality and visual appeal.
These isopods are active surface explorers and appreciate plenty of leaf litter, cork bark, and other natural substrates to maintain a healthy habitat.

These isopods are a great addition to my bioactive enclosure. Their warm coloration stands out and they’re very active, constantly moving around the leaf litter. They’ve helped keep the enclosure clean without needing much maintenance.
Cameron Taylor –
I bought a small group for my terrarium and they’ve been thriving. The buttery brown color is beautiful and they seem to eat the waste naturally. Easy to care for and very hardy.
Pippa Johnston –
They look really nice and are active in their habitat. I noticed they prefer the top layers of leaf litter. They don’t seem to reproduce quickly, but that’s fine for a low-maintenance setup.
