Porcellio ornatus High Yellow Isopods for Sale UK

Few isopods make such a strong first impression. Porcellio ornatus High Yellow pairs broad, almost matte black markings with bold yellow bands and irregular pale flecks. Each segment breaks up the pattern in a slightly different way, so the colour looks striking from every angle without losing the animal’s natural detail.

The shape is just as distinctive as the colour: a long, sculpted Porcellio body with pronounced edges and a tapered rear gives High Yellow a silhouette quite unlike the rounded roller isopods. Seen moving over bark, those sharp lines and high contrast markings really come into their own.

Setting up your colony

Offer a well ventilated enclosure with a moist refuge at one end and a drier area to explore. Provide plenty of cover, a generous layer of leaf litter, and rotting wood as a lasting food source. Keep a calcium source such as limestone available, and avoid letting the entire substrate become waterlogged.

For more on building a moisture gradient and choosing cover, see our isopod habitat setup guide. You can also browse all isopods to compare other shapes and colours.
