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, a band a heated room stays inside for most of the year, 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 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, since a heated home sits inside its temperature band for most of the year. 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. Stagnant, humid air kills this species, which I know from keeping it rather than from a study, 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 while the rest of the floor stays drier than that damp corner, 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 an English home averages about 19°C over the heating season, so a heated room keeps the tub inside the band for most of the year. A room left unheated in winter can drop below 18°C, and there a heat mat or heat cable on a thermostat, fixed to the side of the tub and never underneath, is the fix. 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 still short of their last pair of legs but 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. 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 air moving, 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 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 good place to start.
Does it need a heat mat?
Not in a normally heated room: an English home averages about 19°C over the heating season, inside its 18 to 26°C band. If the room drops below 18°C in winter, add a heat mat or heat cable on a thermostat, on the side of the tub and never underneath.
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.
