Ethmostigmus sp. Borneo Blue
Identity confidence: provisional. This is a genus, group, or trade name rather than a confirmed species. Treat it as the closest match we can stand behind, and use the more conservative end of any range.

Use This Guide Safely
- Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
- Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
- Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.

Enclosure Format / Size Class
- terrestrial burrow setup for larger juveniles
Warnings First
- Fast venomous centipede
- Advanced only
- Solitary housing only; never cohab centipedes
- Secure lid mandatory
- Cross ventilation low on two opposite walls, at substrate level, is the single biggest survivability factor. A humid Borneo setup with no air movement down low is a mold and mite trap.
Simple Care
- Deep moist substrate.
- Cross ventilation low on two opposite walls, at substrate level. Priority one on a humid setup.
- Locked lid.
- Shallow water dish packed with pebbles so small instars cannot drown.
- House singly; centipedes are cannibalistic.
- No handling ever.
Advanced Keeper Notes
Enclosure & Microclimate
- Maintain a humid retreat and deep substrate so the centipede can stay hidden and hydrated.
- Ventilation should prevent mold without drying the enclosure quickly.
- In practice that means cross ventilation at substrate level: vents low on two opposite walls, at or just above the substrate line, so air crosses horizontally through the burrow layer. That is the arrangement that clears stale air from where the animal lives without stripping moisture out of the deep substrate, which a lid vent alone cannot do. Top-only venting dries the surface while saturated air sits still down in the burrow, and that pocket is where cuticle fungus and mite blooms begin.
- Bond fine stainless mesh flush over the low vents, sized under the head width. Ethmostigmus climb enclosure seams well, so the mesh edges matter as much as the mesh gauge.
- Ventilation and ambient humidity are one system with a trade-off built in. Hold 70 to 85% by keeping the lower substrate damp and running a water dish underneath good airflow, rather than by throttling the vents. A sealed humid box shows a perfect hygrometer reading right up to the point the animal gets sick.
- Read the substrate by hand: bottom third clumps and holds when squeezed with no water running out, middle cool and damp, top inch allowed to look dry. That vertical gradient is the microclimate you are actually building.
- Keep a shallow water dish in year round, packed with pebbles or flat stones so the water sits below the rim. Small instars drown in open water and the stones give them a climb-out, and the dish feeds humidity in at floor level so the open substrate can stay less wet.
- Mist under the hide rather than over the whole enclosure. It puts the damp exactly where this species rests during the day and leaves the rest of the box drier with air still moving through it.
Feeding, Growth & Maintenance
- This one is pretty enough that people build the display first and the lockbox second. Do it the other way round.
- Use secondary containment for feeding, cleaning, and transfers.
- Molting: a centipede stops eating and seals into its burrow to molt, staying soft and vulnerable for days. Leave it completely alone, keep all prey out, and don't excavate to check on it.
Possible Origin / Range
- Likely native range: Borneo tropical forest region.
- Habitat translation: Humid tropical substrate with airflow and a secure hide.
Advanced Keeper Details
- Exact species may be uncertain; keep notes on growth, molt intervals, and response to moisture.
- Use deep substrate and a tight lid; tropical centipedes can climb seams surprisingly well.
- Adult size ~6-8 in. Ethmostigmus tend to be a notch less hair-trigger than a Scolopendra of the same size, but 'less defensive' is not 'handleable'; the venom is still potent and the escape risk is identical.
