Captive Dairy Cow morph, recorded as Porcellio laevis by the observer; trade identification, not genetic authentication.Igor Balashov · CC BY 4.0Auto-oriented, downscaled only when larger than 2000 px, and encoded as WebP at quality 92; no crop, retouching, recoloring or biological edits.

Morph / color line

Dairy Cow

Porcellio laevis "Dairy Cow" (trade identification)

Identity & provenance: Commonly sold as Porcellio laevis; that accepted species name does not independently verify captive stock. Dairy Cow is a hobby label.
Conditions vary by stock. Confirm line identity and established care with the supplier.
Reported difficulty: Beginner
Moisture & refuge: Damp refuge plus a drier, ventilated feeding area
Temperature · source wording: Not documented
Breeding notes: Often prolific after establishment; no fixed production schedule
Bioactive suitability: Conditional; evaluate other inhabitants and feeding pressure

Powder Blue Isopod (Porcellionides pruinosus) photographed in France.Alex Abair · CC BY 4.0Resized proportionally when needed and converted to WebP at quality 84; no crop, recoloring, retouching, or biological edits.

Morph / color line

Powder Blue

Porcellionides pruinosus "Powder Blue"

Identity & provenance: Porcellionides pruinosus is an accepted species; Powder Blue is a hobby color label. The label does not independently authenticate every captive line.
Conditions vary by stock. Confirm line identity and established care with the supplier.
Reported difficulty: Beginner
Moisture & refuge: Damp retreats with a less-wet surface and airflow
Temperature · source wording: 72–82°F: The Bio Dude's working range, not a tolerance limit
Breeding notes: Fast in established breeder cultures
Bioactive suitability: Useful where a protected moist refuge is available

How these notes compare

These entries use the exact published care fields from each IsopodAtlas profile, joined to the species directory by profile URL. Each card links to the full article and its sources. Reported difficulty is an editorial care assessment, not a measured survival rating.

Temperature ranges retain their original attribution and limits. A breeder working range is not a tested tolerance or universal optimum. Missing fields say “Not documented”; no ranges, breeding rates, or compatibility scores are calculated.

Morph and trade names do not authenticate captive stock. Conditions vary by stock, enclosure, and colony history. Compare the taxonomy and trade-name guide, then confirm source-colony conditions with your supplier.

Existing approved photographs retain their caption, source, and license. A parent-species reference does not verify a morph or line. Read the moisture-gradient guide and cleanup-crew compatibility guide before applying these notes to a shared enclosure.

Questions before choosing

Does a beginner label mean any enclosure will work?

No. It describes a practical care assessment. Each colony still needs food, cover, ventilation, and a dependable damp refuge. Read the full profile and assess the enclosure you can maintain.

Can I keep the selected isopods together?

This tool compares care notes; it does not recommend mixing colonies. Similar moisture wording does not establish compatibility. Keep line records and assess competition, feeding pressure, and other inhabitants separately.

Are Powder Blue and Powder Orange separate species?

They are hobby color forms associated with Porcellionides pruinosus. A form label and a formal species name answer different questions; neither authenticates an individual captive culture.

Why are some temperature entries words instead of numbers?

The profile may document source-colony practice or uncertainty rather than a numerical range. Replacing that context with an inferred optimum would make the comparison less reliable.
