Porcellio scaber "Arenaria"

Porcellio scaber "Arenaria" is an incredibly unique, highly sought-after, and beautifully colored morph of the common rough woodlouse that adds an elegant, sandy aesthetic to any collection. Native to specific coastal dunes and sandy maritime environments, this specialized wild-caught strain stands out drastically from typical dark grey scaber varieties. They display a gorgeous, soft sand-beige, cream, or light tan coloration, often decorated with varying degrees of subtle orange or pale grey flecks running along their backs. True to its common name of the Rough Woodlouse, its dorsal surface is covered in prominent microscopic bumps and tubercles, giving it a beautifully textured, matte finish that mimics the look of fine sand grains. They are flat-bodied, moderately sized isopods that are unable to roll into a ball, relying instead on their natural camouflage and ability to play dead when startled.

This species is an absolute treasure for entry-level beginners who want a bulletproof starter pet, as well as advanced collectors searching for a rare, highly specialized regional locale. Thanks to their extreme adaptability, hardiness, and active nature, they are perfect for keepers wanting an isopod that is constantly exploring bark and leaf litter rather than staying hidden deep underground. They serve as an exceptional, hard-working clean-up crew for temperate, semi-arid, or coastal bioactive terrariums, efficiently managing waste from small to medium-sized reptiles and amphibians. If you are looking for an unstoppable, fast-establishing isopod that breaks away from standard colors to offer a beautiful, natural desert-sand look, the Arenaria morph is a flawless addition.

SCIENTIFIC NAME: Porcellio scaber "Arenaria"

ORIGIN: Originally isolated from coastal sand dune regions of Western Europe, where their unique pale coloration evolved to blend perfectly with maritime sands.

DIFFICULTY: Very Easy / Beginner

TEMPERATURE RANGE: 18-26°C. They adapt effortlessly to standard room temperatures and tolerate typical seasonal indoor temperature changes with total ease.

HUMIDITY & MOISTURE: 50-60% humidity. They are highly drought-tolerant compared to more sensitive species but still require a dependable moisture gradient. Maintain a strict layout where one-third of the enclosure features a damp, well-misted sphagnum moss patch, while the remaining two-thirds stay completely dry and covered in shelter. They prefer moderate cross-ventilation and will struggle in stagnant, swampy tropical environments.

DIETARY NEEDS: Their foundational diet rests upon a permanent, deep supply of organic deciduous leaf litter and crumbling white-rotted wood. They have a notably high craving for animal matter and should be consistently supplemented at least twice a week with protein sources like dried fish flakes, shrimp, minnows, or insect frass. A continuous source of calcium, such as cuttlefish bone or limestone chunks, is absolutely vital to support their heavily calcified carapaces during their frequent molting cycles.

ACTIVITY LEVELS: Bolder and more surface-active than many cryptic species, they can frequently be seen clumped together under bark or exploring the dry zones of their habitat during daylight and evening hours alike.

REPRODUCTION RATE: Prolific and fast. They are incredibly reliable breeders that establish dense colonies very quickly, producing healthy broods of 12-20 mancae per clutch that rapidly grow to maturity.

SIZES: You will receive a healthy, robust mix of sizes ranging from developing juveniles to young adults, providing an optimal demographic mix to jumpstart your culture. Please note that young juveniles often appear very pale and cream-colored at first, fully developing their rich, sandy tones and characteristic mottling as they grow. Newborn mancae are never intentionally counted or shipped, though some may emerge naturally during transit.

PACKAGING: The isopods are packed with great care inside well-ventilated plastic travel tubs layered with damp sphagnum moss to ensure stable transit humidity. These containers are securely nested inside a sturdy shipping box padded with eco-fill, paper, or thick cardboard to completely insulate the culture from movement and extreme outdoor temperature spikes.
