Hyleoglomeris cf. Bomba
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.
Rubber Ducky Pill Millipede: Advanced Care Guide
Keeper Snapshot: A tiny communal pill millipede. Fussy about humidity. Keep it as a stable small group or culture.
Group: MillipedesDifficulty: Spice 1: Kid FriendlySetup: Humid communal pill millipedeHandling: Brief contact tolerated. Handling is optional and never required for good care, and a fall can injure the animal.
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 groups
Warnings First
- Do not let dry out
- Avoid swampy conditions
- Tiny escape risk
- Wanting it damp but not swampy in a tiny secure box is an airflow problem. Fine mesh low on two opposite walls solves it without opening an escape route.
Simple Care
- Moist but not soaked.
- Gentle fine-mesh vents low on two opposite walls; small openings, but placed where they cross the substrate.
- Use leaf litter and moss.
- Shallow water dish packed with grit: a curled pill millipede cannot right itself in open water.
- Best as a stable small group/culture with fine ventilation.
- Handle as little as possible.
Advanced Keeper Notes
Enclosure & Microclimate
- Keep this species in a small, stable microclimate with leaf litter, moss, and decayed wood.
- Because pill millipedes can be sensitive, avoid frequent substrate disturbance and large food pieces that mold.
- Small groups are appropriate, but crowding and stale wet substrate are not. Add leaf cover and microhabitat stability before adding numbers.
- Stale wet substrate is prevented by vent placement rather than by watering less, which matters because this species will not tolerate you watering less. Put fine mesh low on two opposite walls so gentle airflow crosses the substrate surface while the moss and deep layer hold moisture. That is how you keep a small culture damp and aerobic at the same time.
- Ventilation and ambient humidity trade against each other, and the resolution is to carry the moisture in the substrate rather than in the air. Then the airflow can stay generous without drying the animals out.
- Judge by squeeze and smell rather than by a gauge that will not fit a culture box. Lower substrate clumps like a wrung-out sponge, releases no free water, and smells like forest floor. Sour means airflow and fresh substrate.
- Keep a shallow dish packed with coarse grit so the waterline sits below the rim. A pill millipede that curls in water cannot right itself, which makes open dishes a real hazard for this group rather than a theoretical one.
- Mist into the moss and under the leaf litter rather than soaking the box. That maintains the stable damp microclimate the species needs without the frequent substrate disturbance the note above warns against.
Feeding, Growth & Maintenance
- Fine ventilation is important to prevent escapes and preserve humidity.
- Do not keep this like a hardy isopod. It is not one.
- Molting: pill millipedes molt sealed away in the substrate and stay soft for a while afterward. Don't disturb buried animals or dig to check, keep that zone from drying out, and keep cuttlebone available since they eat the shed to reclaim calcium.
Possible Origin / Range
- Likely native range: Southeast Asian limestone or forest trade stock; exact locality is often supplier-dependent.
- Habitat translation: Humid forest-floor setup with calcium or mineral access and deep leaf litter.
Advanced Keeper Details
- The cf. label means ID is provisional; keep locality and vendor notes with the colony.
- Communal culture is normal for this type, but a culture is only as stable as its moisture gradient, calcium, leaf litter, and ventilation.
- Avoid rapid moisture swings; small pill millipedes crash fast when substrate dries.
