Quick answer
The Redhead is Armadillidium flavoscutatum from Albania, a glossy near-black pill woodlouse with a vivid red-orange head shield, and the whole trick to keeping it is remembering that it is Mediterranean, not tropical. Give it 18 to 26°C, which an ordinary UK room provides all year without heating, moderate humidity around 50 to 70 per cent arranged as a drier main area with one damp retreat, good airflow, and constant calcium. Do that and it is one of the easiest genuinely striking isopods in the hobby, and one of the quickest of its genus to build a colony.
The species, and where the Redhead came from
Most keepers meet Armadillidium flavoscutatum as the spotted "clown" form, patterned in yellow and white. The Redhead is a different animal to look at: a locality found in Albania in the summer of 2023 that drops the spotting for a clean, lacquered, dark body crowned with that bright head shield. It is still fairly fresh in the hobby, which gives it a little of the new-locality collector appeal, but underneath the looks it keeps everything that makes the genus dependable: it is hardy, calm, and thoroughly suited to keeping in this country, because a European animal is built for exactly the temperatures and seasonal swing a UK home provides. It sits in our Armadillidium collection with the rest of the rollers, and our complete Armadillidium guide covers the genus around it.
Appearance
A medium-to-large Armadillidium at roughly 18 to 20 mm. The body runs glossy dark brown to near-black with a real shine to the finish, and the head shield carries the red-orange that names the form. The contrast is the appeal, and it is already visible on young animals, deepening as they mature. They are true pill woodlice and roll into a tight ball when disturbed, and a dark, polished bead topped with red is a particularly handsome thing to find under a piece of cork.
Conditions: Mediterranean, not tropical
This is the one point on which the Redhead punishes a misunderstanding. It wants moderate humidity, around 50 to 70 per cent, and it wants most of the floor on the drier side of that with a single damp retreat, not a uniformly moist tub. Overwetting and stagnant air are a far bigger risk than a slightly dry spell, so when in doubt, err drier and turn the ventilation up. Build the moisture as a gradient: one corner kept damp under lightly misted sphagnum, the rest of the floor left to dry between waterings, and vents on opposing sides so air actually moves across the enclosure. A gradient only exists if the dry end is genuinely dry, and airflow is what keeps it that way.
Temperature is the easy half. A range of 18 to 26°C works the year round, and normal UK room temperature sits inside it in every season, so there is no heating to buy and no thermostat to set. Our guide to humidity for isopods goes deeper on why the gradient matters more than any single figure.
Substrate and calcium
Give 5 to 8 cm of organic topsoil and flake soil with white-rotted wood through it, topped with hardwood leaf litter and a piece of cork for cover. Leave plain coco coir out of the base, since a substrate the animals cannot eat is bedding rather than habitat. Like every Armadillidium the Redhead builds a heavy, calcium-hungry shell, so mix crushed limestone or eggshell through the substrate and keep cuttlebone permanently available; our calcium guide covers the mineral side that heavy breeders lean on.
Feeding
An unfussy detritivore. Hardwood leaf litter and decaying wood always down, vegetable once or twice a week, occasional fruit, and a regular pinch of protein, which this prolific breeder puts straight into broods. Lift uneaten fresh food within a day or two, and run a springtail culture in the damp corner to keep it clean.
Breeding
This is the Redhead's real strength, and the reason I recommend it so readily as a first Armadillidium beyond the classics: once its moderate, drier-side conditions are met it breeds easily and throws notably large broods, so a colony builds quickly and reliably. Young emerge fully formed, already showing the red head, and colour up as they grow. Give gravid females a few extra hides, hold the conditions steady, and it does the rest. Start with a decent group, twenty or more if you can, and resist the urge to check on them daily while they settle.
Common mistakes
Treating it as tropical is the big one: a soaked, sealed, heated tub is the opposite of what an Albanian hillside provides, and it is the quickest way to lose a colony. The others are letting the whole floor dry to dust with no damp retreat at all, and forgetting calcium, which for a big-shelled roller shows up first as failed moults. Set the gradient, keep the airflow honest, leave the calcium in permanently, and there is very little that goes wrong with this species.
Who is it for, and what sits alongside it
The Redhead suits the beginner who wants something distinctive without demanding care, the collector drawn to a recently found locality, and the display keeper who would rather actually see their animals, since this one is calm and out and about across the day. On the shelf it pairs naturally with the boldly striped Zebra and the classic Gestroi, and if the dark end of the genus appeals, the Darth Vader and the neat little Esterelanum run on the same drier Mediterranean routine and make easy companions in a collection.
Frequently asked questions
Is the Redhead good for beginners?
Yes, with one caveat: you must believe the Mediterranean part. Keepers who set it up like a hardy European species succeed immediately; keepers who set it up like a Cubaris drown it in kindness. If this is your first isopod, its forgiving temperature range and quick breeding make it a genuinely good place to start.
Does it need a heat mat?
No. An ordinary UK room sits inside its 18 to 26°C band all year. If your room runs unusually cold in winter it will simply slow down rather than come to harm within that range.
Why is mine always hidden?
It usually is not, which is part of the appeal, so a colony that vanishes is telling you something about conditions, most often that the tub is too wet and the animals are pressed into whatever dry refuge they can find. Dry the main floor out, lift the airflow, and they come back out.
Will the red fade?
No, it deepens. Young animals show the head colour faintly and it intensifies with each moult, so a colony gets better looking as it matures.
