Porcellio expansus are large, ornate Isopods that look prehistoric. They are one of the most popular pet species due to their amazing size, coloration, and antenna length. These are native to Spain, and are a classic large Spanish species. Our isopods are fed Iso-licious Isopod Food 1-2x a week, including our new wet mixes, supplemented with potatoes, squash, carrots, our leaf powder, and a cuttlebone. These isopods enjoy warm temperatures and an occasional misting, but do not do as well in a wet environment. We allow space for a extensive moisture gradient, starting with one side of the enclosure having moist NZ sphagnum moss, the middle being mostly dry and covered with leaf litter and bark, and onto the opposite side being bone dry and covered only with leaf litter. This provides the needed space for Isopods to osmoregulate to remain in homeostasis. These are semi-arid species and require ventilation for optimal health.
