Porcellio sp. Sevilla ‘Wild’ Isopods - Woodlouse Culture
A larger isopod species with a grey-brown colouring and clean white skirting.
Porcellio sevilla are one of the 'Spanish Giants' and require slightly different care to most isopods. These hail from Southern Spain so prefer dryer conditions with a smaller moist corner, around a third of their enclosure in size. There has been speculation that this species and Porcellio hoffmannseggi are very closely related or even the same in some instances, but more research is needed to confirm this. For now, these are considered a different species and will be treated as such.
This species is super active and can be seen out in the open exploring their tank and munching on decaying leaf litter. We find these like a thick layer, at least 5cm, of leaf litter topped off with curved bark pieces which allows them to escape excess humidity. They will also settle quickly in a tank with lots of surface area and hiding spots and are prolific breeders once happy. Too much humidity causes fast die-offs with this species, so its important to not over spray and have excellent ventilation. Like other larger species of isopod, these require a constant source of calcium, so a large cuttlebone or supplement can be left in their tank at all times.

- We suggest keeping P. sevilla between 21-23˚C and 50-60% humidity for best results. This species comes from Spain and prefers it on the drier side, so a well ventilated container or faunarium can be used. This species will settle and breed well with a 5-10cm layer of leaf litter, wood and bark above their substrate level. These are a big species so need more space than most species. We keep a large colony of isopods in a 40x20x20cm critter keeper with vent holes across the lid. A smaller colony of 10-15 will do just fine in a 20x15x15cm enclosure.
- Like other isopods, these need a humidity gradient which can be achieved by making sure there are dry and damp areas in their environment. The best way is to provide sphagnum moss or live moss in one third of the enclosure as a 'hydration station' and keep this constantly moist. We suggest keeping the substrate moist (not soaking!) and provide plenty of bark pieces and leaf litter to allow them to seek out dryer spots.
- Make sure you use a high-quality substrate (no coco coir!) such as our Premium Millipede Edible Substrate as this will be the main food component for your isopods, and provide crushed cuttlebone or eggshells for calcium, as well as a good quality protein source once a week for optimal health. We prefer to feed vegetables to our isopods to help deter fruit fly and fungus gnat infestations, but that’s just our choice! Like many invertebrates one of their favourites is cucumber which we provide in slices and replace once completely eaten, which is around once a week.
- We recommend not keeping any protein-hungry isopods with millipedes as they can sometimes nibble on them whilst molting!
