Pink Dragon Millipede (Desmoxytes Planata)

The Pink Dragon Millipede is one of the most visually distinctive millipedes in the hobby — vivid pink colouration paired with a spiny, draconic body shape that looks almost prehistoric. Desmoxytes planata belongs to a genus of Southeast Asian millipedes famous for their striking appearance and equally striking chemical defences. This is a species for keepers who want something genuinely unusual, not a beginner's first millipede.

A Glimpse

• Scientific Name: Desmoxytes planata
• Common Names: Pink Dragon Millipede, Shocking Pink Dragon Millipede
• Family: Paradoxosomatidae (Order Polydesmida)
• Origin: Southeast Asia — native to Thailand, Vietnam, and surrounding regions. Has been recorded from Sri Lanka, the Andaman Islands, Seychelles, Java, and Fiji due to human-assisted dispersal.
• Adult Size: Approximately 3 cm (30 mm)
• Difficulty: Moderate to Hard — the care itself isn't complicated, but the cyanide defence makes them a non-beginner species
• Temperature: 24–28°C
• Humidity: High — 70–90%
• Lifespan: 1–2 years typical for Polydesmida species
• Defence mechanism: Produces hydrogen cyanide (see safety section below)

⚠️ Issues on the Current Page

A few corrections worth flagging before we go further — these are mistakes on the current listing that should be updated:

• Origin is wrong. Current page shows "Ghana / Nigeria (West Africa)" — this is copied from the Chocolate Millipede listing. Desmoxytes planata is a Southeast Asian species native to Thailand and Vietnam, not West Africa. This needs correcting in the care icons.
• Size is dramatically wrong. Current page shows "200–260 mm" — also copied from the Chocolate Millipede (which is a giant species). Pink Dragon Millipedes are tiny: approximately 30 mm (3 cm) as adults. Two orders of magnitude out.
• Difficulty is wrong. Current page shows "Easy" — these are not easy millipedes. They produce hydrogen cyanide, need tropical conditions, and have short lifespans. More accurate would be Medium-Hard.
• Rarity is debatable. "Common" is generous. They're not frequently available in the UK hobby and are more accurately rated Uncommon to Rare.

The temperature (24–28°C) and humidity (60–80%) on the care icons are in the right range, though humidity should probably be higher — 70–90% is typical for this species in the wild and in captivity.

The Pink Dragon Look

Desmoxytes planata belongs to the "dragon millipede" genus, named for the distinctive body shape: each body segment has lateral extensions (paranota) that project outwards and angle upwards, giving the animal a spiny, winged, almost Chinese-dragon silhouette. Combined with the vivid pink to purple-pink colouration, the effect is striking. They look more like ornate jewellery or fantasy creatures than typical millipedes.

The bright pink is aposematic — warning colouration telling potential predators that the animal is toxic. In the wild, Pink Dragons often rest openly on vegetation and leaf litter during the day, something most millipedes wouldn't dare do. Their chemistry is sufficient protection that they don't need to hide.

For a small millipede (adults top out around 3 cm), they have enormous visual impact. In a well-lit display enclosure, they're one of the most photogenic inverts in the hobby.

⚠️ Hydrogen Cyanide Defence — Read This Before Buying

This is the most important thing to understand about Pink Dragon Millipedes. Like all species in Order Polydesmida, they produce hydrogen cyanide from defensive glands along their body when threatened or stressed. You'll often smell it — the distinctive almond-like odour is a telltale sign they've released their defence compounds.

What this means in practice:

• Don't handle them with bare hands. The cyanide secretion can cause skin irritation, and you shouldn't be exposing your skin to a cyanide-producing animal regardless. Use soft tweezers or a paintbrush if you need to move them, or tip them gently into a container.
• Don't keep them in sealed containers. In a fully enclosed space with poor ventilation, a stressed colony could theoretically build up cyanide concentrations to levels that harm other small invertebrates in the enclosure. Proper ventilation isn't just husbandry — it's a safety measure.
• Wash hands after any contact with the enclosure, substrate, or animals. Don't touch your face, eyes, or mouth until you have.
• Not suitable around children who might handle them. These aren't a pet to pass around for casual handling. They're a display species.
• Don't keep with other invertebrates. Mixed species enclosures are a bad idea with any millipede, but particularly with Polydesmida. The cyanide secretion can harm tankmates.

None of this makes Pink Dragons dangerous pets for responsible keepers — the amount of cyanide produced is small and the risks to humans from casual contact are minimal. But it does mean they're not an impulse buy or a species for beginners who might not understand the implications.

Enclosure

A well-ventilated tropical enclosure is essential. Good airflow prevents cyanide buildup (see safety section above) and also prevents the mould and stagnant-air issues that plague poorly-ventilated humid setups.

Minimum enclosure size for a group of 5–10 is around 15–20 litres. They don't need enormous space, but they do benefit from horizontal surface area where they can forage across leaf litter. A standard glass terrarium or plastic tub with a well-ventilated lid works fine. Use cross-ventilation — vents on opposite sides — rather than a single vent area, to keep air moving through the enclosure.

Our accessories collection has suitable air vents for building properly ventilated tropical setups.

Substrate

Pink Dragons need a deep, moist, organic substrate — their entire life revolves around decomposing leaf litter and rotting wood.

Base: Organic topsoil (pesticide-free) mixed with flake soil for nutrition. Aim for a depth of 5–8 cm. The substrate should hold together when squeezed but not drip.

Middle layer: Pieces of rotting white hardwood and kinshi. As a Polydesmida species, D. planata feeds heavily on decomposed wood broken down by fungi — kinshi is biologically ideal for them.

Top layer: Generous leaf litter covering the entire substrate surface. Magnolia leaves provide long-lasting cover and bamboo leaf litter adds structural variety while keeping the layer airy.

Moisture: Keep the substrate consistently damp, not waterlogged. Mist regularly to maintain humidity at 70–90%. The deep substrate should hold moisture well between mistings.

Temperature

24–28°C is the target range. Room temperature in most UK homes during summer will be suitable, but during winter you'll likely need supplementary heat. A low-wattage heat mat on the side of the enclosure (not underneath, to avoid drying the substrate) paired with a thermostat is the standard approach. Don't let temperatures drop below 22°C consistently — Pink Dragons are genuinely tropical and don't tolerate cool conditions well.

Diet

Primary diet is decaying leaf litter and rotting hardwood. Always have both available in the enclosure. Supplementary foods can include:

• Thin slices of fruit and vegetables (cucumber, courgette, sweet potato) — offered sparingly
• Fish flakes or dried shrimp as occasional protein
• Cuttlebone for calcium — important for healthy moulting
• Limestone pieces as a passive calcium source

Remove uneaten fresh food after 24–48 hours. Protein and fresh produce spoil quickly in high-humidity tropical setups and can cause mould and mite issues.

Breeding

Breeding Desmoxytes planata in captivity is possible but not always straightforward. Females lay eggs in the substrate, and hatchling millipedes are tiny and hard to spot. Adults have relatively short lifespans (1–2 years), which means successful breeding is essential for maintaining a colony long-term. The good news is that Pink Dragons don't seem to have the complex breeding requirements some tropical millipedes do — consistent conditions and good food quality tend to produce offspring if you have both sexes present.

Start with a group of 5–10 to maximise the chance of having both sexes. Sexing individual Pink Dragons isn't practical for most keepers, so colony purchases are the reliable approach.

Compared to Other Millipedes We Stock

If you're deciding between millipede species, here's how Pink Dragons compare:

• vs Chocolate Millipede or Ghana Speckled Leg: Completely different category. The African giants are long-lived (7–10 years), large (20+ cm), and don't produce significant cyanide defences. They're better first millipedes for most keepers. Pink Dragons are small, short-lived, visually stunning, and chemically defended.
• vs Red Fire Millipede or Amber Millipede: The brightly-coloured Spirobolida species are also aposematic but much less chemically potent. Pink Dragons produce more concentrated cyanide.
• vs Thai Rainbow Millipede: Thai Rainbows are also Southeast Asian Polydesmida — similar cyanide defence, similar care requirements. If you want another dragon-style millipede with different colouration, Thai Rainbow is a logical companion choice.
• vs Tiny Polydesmus Millipede: Same order (Polydesmida), same cyanide chemistry, much smaller size. Polydesmus are a good way to get experience with Polydesmida-family care before committing to Pink Dragons.
