Armadillidium nasatum "Peach"
Peach isopods are a color form of Armadillidium nasatum. Learn their parent-species identity, enclosure, moisture, food, breeding, and common problems.
Peach is a hobby color form of Armadillidium nasatum, the nosey pill-woodlouse. It is not a separate species, and not every wild A. nasatum is peach-colored.

Peach isopods are pale warm-colored stock sold as Armadillidium nasatum. Keep them as a documented color line with a covered damp refuge, ventilated substrate, and a steady litter supply. The peach label does not establish a separate species or a different set of proven physiological requirements.
Parent species and the Peach label
BMIG identifies A. nasatum, the nosey pill-woodlouse, by a projecting snout-like structure on the head. Typical wild animals are often gray with pale longitudinal markings; the species can also occur in colored forms. Parent-species body length is reported up to about 12 mm.
Keepers and sellers use Peach for selected pale-colored stock. Do not confuse it with Magic Potion, which is associated with A. vulgare, or with Powder Orange. A light orange photograph cannot substitute for a documented species label.
Enclosure and substrate
Use a secure, screened container with space for a damp refuge and a less-wet area. Cover an organic, moisture-retaining substrate with leaves and a stable hide. Keep the substrate useful as shelter rather than reducing it to a thin display layer.
Offer cover through the transition between zones. A patch of soaked moss surrounded by bare dry ground does not give small juveniles many protected choices. The enclosure guide covers layout and vent placement.
Moisture, temperature, and ventilation
Parent-species field records include relatively dry exposed habitats, but those records do not describe conditions beneath every shelter. In captivity, retain damp substrate under cover throughout the watering cycle. Inspect there instead of trying to make every part of the bin match one humidity reading.
Match the source culture's established temperature conditions and avoid direct sun or uncontrolled heating. The evidence reviewed here does not establish a special Peach temperature target. Screen ventilation and check drying after changing lid openings or moving the culture to a new room.
Diet, calcium, and protein
Provide continuing leaf litter, decaying wood, and an accessible calcium source. Offer small supplements where leftovers are easy to remove. Peach coloration is not a reason to use a different calcium dose or extra protein.
Do not replace leaves with fruit just because the animals gather around it. A conspicuous feeding response says little about whether the whole diet remains balanced. Reduce portions if food repeatedly molds before it is consumed.
Breeding and keeping the line
Springtails US describes productive A. nasatum cultures, but that report is about keeper experience with the species, not a guarantee for every Peach colony. Record juveniles and their development instead of expecting a first-brood deadline.
Maintain the line separately if color and provenance matter. Do not publish inheritance percentages from a generic recessive-trait example without records for the stock you actually have. The trade-name guide explains how to keep line evidence useful.
Our beginner assessment assumes a monitored separate culture. Before using Peach animals in a display, establish a reserve and check whether predation or the display's watering cycle will undermine the colony.
FAQ
Is every Armadillidium nasatum a Peach isopod?
No. Peach describes a hobby color form. Typical wild coloration and other forms also occur within the parent species.
Is a normal gray nasatum photo suitable for a Peach card?
It can illustrate parent-species morphology if clearly labeled, but it should not be presented as a photograph of the Peach morph. This profile does not substitute another color form for the missing morph photograph.
Does pale color mean an animal is unhealthy?
Color alone cannot diagnose health, particularly in a pale-selected line. Assess behavior, continued feeding, shelter conditions, and mortality trends.
Why did the colony decline after I changed substrate?
Review the new material's source, moisture, temperature, and handling together. Use the colony-decline checklist and keep suspect material separate from healthy cultures.
