Armadillidium vulgare
Laboratory studies show relatively effective resistance to water loss compared with some other woodlice. This does not remove the need for a damp refuge.

Give your isopods a choice. Design wet and dry zones, connect sheltered spaces, and keep a field journal of the world beneath the leaves.

TOP VIEW / ILLUSTRATIVEMOIST≋ TRANSITIONDRIER
Drag objects or select one and use arrow keys. Moss sets the water source. In observation mode, click the map to mark a sighting.
SCENARIO ONLY — colors and drying rates use illustrative, uncalibrated rules. This is not measured RH, substrate water content, a watering schedule, a safety rating, or a prediction of animal behavior.
What changes after watering?
Move through an illustrative drying story. Compare possibilities; check the real substrate before changing care.
Let the colony tell its story.
Enable marking, click the habitat map, then save your observation. Multiple dots belong to one entry.

Different species. Different choices.
Porcellio scaber
Sheltering and aggregation contribute to its response to microclimate. Observe covered spaces as well as the damp-to-drier transition.
Oniscus asellus
Research reports greater susceptibility to water loss than A. vulgare under tested conditions. Pay particular attention to retained damp shelter.
Cubaris / Unknown
A genus or trade label is not a single care profile. Defaults are illustrative only. Identify the species and seek species-specific evidence.
Look below the surface
Record conditions at repeatable locations and depths. Air RH and substrate water content are different measurements. Note instrument, time and placement with each reading.
A map, not a verdict
The model combines distance from moss, an arbitrary drying factor, depth and nearby vents. Dashed links connect shelter objects geometrically, not observed animal paths.
A little more understanding.
Is the percentage actual humidity?
No. It is a designed map extent. RH, water content and this illustrative layer are different concepts. No sensor data is inferred.
When should I water again?
The day slider cannot answer that. Check the actual substrate, shelter conditions, ventilation and your species-specific care guidance.
Why are all the isopods in one corner?
Moisture is only one possible influence. Light, temperature, shelter, food and social interactions can also affect aggregation. Record several factors before interpreting it.
Does the dashed line mean a safe route?
No. It shows geometric shelter connections only. It does not evaluate safety, species suitability or actual movement.
