Porcellio scaber “Lava” 

Overview

Porcellio scaber Lava isopods are live captive-bred isopods known for their bold lava-like patterning, active behavior, and reliable culture growth. This listing is for Porcellio scaber “Lava,” a colorful morph of the common rough woodlouse.

These isopods are a great option for keepers who want a hardy display species with more color than standard gray Porcellio scaber. In addition, they can work well in suitable bioactive terrariums when the enclosure has the right moisture balance, leaf litter, and hiding areas.

Scientific Name: Porcellio scaber

Common Name: Lava isopods

Morph Name: Lava

Pronounced: por-SELL-ee-oh SKAY-ber LAH-vuh

Care Level: Beginner to intermediate

Porcellio scaber is widely kept in the hobby because it is adaptable, active, and usually forgiving when basic care needs are met. However, like all isopods, Lava isopods still need a stable moisture gradient, proper food, calcium, and safe hiding places.

Appearance and Size

Lava isopods are one of the most eye-catching Porcellio scaber morphs. Their bodies usually show a mix of dark gray, black, orange, and red-orange markings. As a result, each colony can display natural variation from individual to individual.

Adult Size: About 12 to 17 mm

Their bodies have the rough, textured look typical of Porcellio scaber. This texture helps give the morph a rugged, volcanic appearance. Because of the contrast between the dark base color and warm orange markings, Lava isopods are easy to enjoy in a display culture.

They are also fairly active compared with many more secretive isopods. However, activity will still depend on lighting, humidity, cover, and how recently the colony has been disturbed.

Reproductive Rate: Moderate to fast once established

A healthy Lava isopod colony can grow steadily when temperatures, moisture, food, and calcium are consistent. However, new colonies may take time to settle before visible baby isopods appear.

Lava Isopods Care

Lava isopods are hardy, but they should not be kept bone dry. Instead, provide a clear moisture gradient. One side of the enclosure should stay moist with sphagnum moss or damp substrate. The other side should remain more ventilated and slightly drier.

This setup lets the isopods choose the conditions they need. It also helps prevent both dehydration and overly wet, stagnant conditions.

Best care basics:

• Keep one side moist at all times
• Keep the opposite side more ventilated
• Provide deep leaf litter
• Add decaying hardwood when available
• Offer cork bark or hardwood bark hides
• Provide calcium at all times
• Avoid soaked substrate with no airflow
• Avoid letting the entire culture dry out

Lava Isopods Husbandry

Temperature

Lava isopods usually do well at normal room temperatures.

Recommended Range: 68 to 78°F

Acceptable Short-Term Range: About 65 to 80°F

For best results, avoid extreme heat. In addition, avoid placing the culture in direct sun, near a window, or beside a heat source that can dry the enclosure quickly.

Humidity

Recommended Humidity: Moderate overall humidity with a moist retreat

Lava isopods do best when they can move between moist and drier zones. Therefore, the goal is not to keep the entire container wet. Instead, keep one mossy area consistently damp while allowing the rest of the enclosure to breathe.

A good setup includes:

Moist sphagnum moss on one side

Leaf litter across most of the surface

Cork bark or hardwood bark hides

Substrate that holds moisture without becoming swampy

Ventilation holes to reduce stale air

If you see isopods gathering only on the wet side, the culture may be too dry. However, if food molds quickly and the substrate smells sour, the setup may be too wet or poorly ventilated.

Isopod Container Habitat

A starter culture can be kept in a small ventilated plastic container while it grows. As the colony expands, it can be moved into a larger culture bin, planted terrarium, or bioactive enclosure.

For a simple Lava isopod culture, use:

• Organic substrate or isopod-safe soil mix
• Leaf litter
• Decaying hardwood
• Cork bark or hardwood bark hides
• A moist moss zone
• Calcium source
• Light cross ventilation

Leaf litter is especially important. It provides cover, grazing surface, and long-term food. Decaying wood also supports natural feeding behavior, especially for Porcellio species.

For display enclosures, add more bark, moss, and leaf litter so the isopods can hide and breed safely. However, avoid over-cleaning the habitat. A mature isopod culture works best when it has natural layers to graze on.

Lava Isopods Diet

Lava isopods are detritivores, which means they feed heavily on decaying organic matter. A balanced diet supports stronger growth, better reproduction, and a healthier colony.

Fiber-Based Foods

Fiber-based foods should form the foundation of the diet.

Good options include:

Dried hardwood leaf litter

Decaying hardwood

Cork bark grazing surfaces

Rotten wood

Flake soil

Isopod-safe botanical materials

Leaf litter should always be available. It is not just decoration. Instead, it acts as food, shelter, and humidity support.

Vegetable-Based Foods

Vegetables can be offered in small amounts as supplemental food.

Good options include:

Carrot

Squash

Zucchini

Sweet potato

Pumpkin

Leafy greens in moderation

Remove uneaten vegetables before they spoil. This helps reduce mold, mites, and fungus gnat issues.

Protein-Based Foods

Lava isopods benefit from occasional protein. However, too much protein can foul the enclosure.

Good protein options include:

Dried shrimp

Fish flakes

Freeze-dried insects

TC INSECTS Isopod Food

High-quality isopod diet blends

Offer protein lightly once or twice per week, depending on colony size. Larger colonies may eat more, while starter cultures need only small amounts.

Feeding Notes

Feeding Notes: Feed lightly at first. Then increase food only when the colony is eating it quickly.

Overfeeding is one of the most common beginner mistakes. Therefore, it is better to feed smaller portions more often than to leave large amounts of fresh food in the enclosure.

Always provide calcium. Cuttlebone, limestone, calcium carbonate, or reptile-safe calcium sources can help support molting and reproduction.

Lava Isopods Breeding

Lava isopods usually breed well once established. A new culture may hide for the first few days or weeks after shipping. After they settle, you may begin to see small mancae, which are baby isopods.

Females

Females: Female isopods carry developing young in a brood pouch called a marsupium. Once conditions are stable, mature females can produce repeated broods over time.

Males

Males: Males help maintain colony reproduction, but customers do not usually need to separate or identify males and females in a normal starter colony. A mixed live culture should be allowed to settle and breed naturally.

Colony Maintenance

To support breeding:

• Keep the moss side moist
• Keep leaf litter available
• Add small protein feedings
• Provide calcium at all times
• Avoid frequent digging
• Avoid sudden humidity swings
• Remove spoiled food
• Refresh substrate as needed

Lava isopods are usually productive, but colony speed depends on temperature, food, moisture, and starting group size. Larger starter groups often establish faster because more mature animals are present.

Lava Isopod Natural Habitat

Porcellio scaber is commonly known as the rough woodlouse. The species is native to Europe but is now widely established in many parts of the world. It is often found in damp, sheltered places with decaying organic matter.

In nature, Porcellio scaber is commonly associated with leaf litter, logs, rocks, gardens, forests, meadows, and other protected microhabitats. These habitats explain why captive cultures need cover, decomposing plant matter, and access to moisture.

The “Lava” morph is a captive-bred color form, not a separate wild species. Therefore, the care goal is to support the biology of Porcellio scaber while preserving the colorful morph through captive breeding.

Best Uses for Lava Isopods

Lava isopods are useful for several types of keepers.

They are a strong choice for:

• Bioactive terrariums with suitable humidity
• Display isopod cultures
• Starter isopod colonies
• Planted vivariums
• Maintenance cultures
• Reptile habitats with safe conditions
• Amphibian habitats with proper ventilation and moisture balance
• Educational setups
• Color-focused isopod collections

They are not usually sold as a primary feeder isopod. While some animals may eat isopods if they find them, Lava isopods are better valued as a display, breeding, and cleanup crew species.

For bioactive setups, make sure the enclosure is safe for isopods before adding them. Very dry, very hot, or heavily disturbed enclosures may prevent the colony from establishing.

Receiving and Acclimation Guidance

When your Lava isopods arrive, open the package promptly and inspect the culture carefully. Some isopods may hide in the substrate, moss, paper, or packing material, so check slowly before assuming the count.

After inspection, place the isopods into a prepared culture or enclosure with moist moss, leaf litter, and hides already in place. Then give them time to settle.

To acclimate safely:

• Open the cup carefully
• Inspect the contents in good light
• Move isopods gently into the enclosure
• Add shipping substrate if it looks clean and safe
• Place them near the moist side and leaf litter
• Avoid handling them repeatedly
• Keep the enclosure stable for the first week

It is normal for Lava isopods to hide after shipping. They may stay under bark, moss, or leaf litter while they recover from transit. As a result, you may not see much activity right away.

Avoid adding them to a dry enclosure. Also avoid placing them directly under strong heat or bright light. Stable moisture, cover, and food will help them establish faster.

Final Notes

Porcellio scaber “Lava” is a colorful, hardy, and rewarding isopod morph for the right setup. It offers strong display value while still being practical for many bioactive and breeding projects.

For best results, give the colony moisture choices, plenty of leaf litter, calcium, and time to establish. With steady care, Lava isopods can become an active and productive part of your TC INSECTS isopod collection.

Great choice for reptile, amphibian, and bioactive hobbyists who want color and function

Care and Receiving Guidance

Open your package as soon as it arrives. Then inspect the culture in a calm, well-lit area. Isopods often hide in substrate, moss, paper, or packing material, so check carefully and gently.

Prepare the enclosure before moving the isopods. The setup should already include moist substrate, a damp moss area, leaf litter, hides, and calcium. This helps reduce stress during transfer.

Place the isopods near the moist side of the enclosure. Next, add leaf litter over part of the area so they can hide quickly. After that, leave the colony mostly undisturbed while it settles.

It is normal for Lava isopods to hide after shipping. In many cases, they will become more visible after they adjust to the new enclosure. However, they may stay hidden if the setup is too dry, too bright, or too exposed.

Good establishment conditions include:

• A moist moss retreat
• A drier ventilated area
• Deep leaf litter
• Cork bark or hardwood bark hides
• Stable room temperature
• Small feedings
• Constant calcium access

Beginners should avoid overfeeding, over-misting the entire enclosure, letting the culture dry out, and checking under every hide too often. Instead, keep conditions stable and allow the colony to build naturally.

Best Uses for Lava Isopods

Lava isopods are best used as a colorful display species, breeding colony, and cleanup crew for suitable bioactive enclosures.

Bioactive Terrariums

Lava isopods can help break down shed skin, leftover organic matter, leaf litter, and soft decaying material. However, they still need safe humidity, cover, and food.

Starter Colonies

Because Porcellio scaber is generally hardy and adaptable, Lava isopods can be a good starter isopod for keepers who are ready to maintain a moisture gradient.

Display Cultures

Their orange and dark mottled pattern makes them much more visually interesting than many standard cleanup crew species.

Maintenance Cultures

Keep a separate culture if you plan to seed multiple terrariums over time. This protects your main colony and gives you a backup supply.

Reptile Habitats

They can work in reptile enclosures that are not too dry or hot. Provide leaf litter and safe hides so the isopods can avoid constant disturbance.

Amphibian Habitats

They can work in many planted amphibian setups, especially when ventilation prevents stagnant conditions. However, avoid waterlogged substrate.

Planted Vivariums

Lava isopods pair well with springtails in planted vivariums. Together, they help process organic material at different levels of the substrate.

Assorted Hardwood Leaf Litter

Assorted Hardwood Leaf Litter is one of the most important materials for isopods. It provides food, shelter, surface cover, and humidity support. Many isopods naturally live under layers of decaying leaves, so leaf litter helps create a more natural culture environment.

A good layer of hardwood leaf litter helps reduce stress, gives isopods more places to hide, and provides a long-lasting food source as the leaves slowly break down. Leaf litter should be available in every isopod culture.

Best for:

• Every isopod culture
• Natural food source
• Hiding cover
• Humidity support
• Reducing stress in new colonies

 ISO-COAL Isopod Charcoal Hides

ISO-COAL Isopod Charcoal Hides give isopods dark, protected areas where they can gather, hide, molt, and breed. Hides are important because isopods feel more secure when they have covered areas inside the culture.

These hides also make it easier to check colony activity because many isopods will gather underneath them instead of staying buried deep in the substrate.

Best for:

• Isopod culture bins
• Breeding colonies
• Molting support
• Reducing stress
• Easy colony checks

Shop TC INSECTS ISO-COAL Isopod Charcoal Hides

TC Calcium Ultra Fine

TC Calcium Ultra Fine is an important add-on for isopods because calcium supports healthy molts, exoskeleton development, and long-term colony growth. Isopods use calcium as they grow, reproduce, and rebuild their outer shell after molting.

To use, offer a very small amount in the isopod culture. You can also add a little water to the calcium powder to make it look like a light paste, then place a small portion in the enclosure so the isopods can access it as needed. Avoid adding too much at one time, and replace it if it becomes dirty, overly wet, or moldy.

This is especially useful for larger isopod species, breeding colonies, premium Cubaris species, and fast-growing cultures.

Best for:

• Healthy molts
• Strong exoskeleton support
• Breeding colonies
• Larger isopod species
• Cubaris species
• Long-term colony growth
