Hyleoglomeris sp. “Ducky” is a small, vividly patterned pill millipede known for its yellow facial markings and rounded, toy‑like appearance. Like all members of the genus Hyleoglomeris, it can roll into a perfect sphere when disturbed, relying on this behaviour rather than speed or aggression. The “Ducky” form is a trade name rather than a formally described species, but it is associated with humid forest‑floor habitats in Southeast Asia where leaf litter, decaying wood and stable moisture create the microclimate these millipedes depend on.
 
In captivity, “Ducky” pill millipedes thrive in deep, structured substrates rich in leaf litter and rotted hardwood. They prefer warm, humid conditions with gentle cross‑ventilation to prevent stagnation while keeping moisture locked in. Their diet is almost entirely decomposed plant matter, though tiny additions of vegetables or protein dust can support growth. They are communal, slow-moving and secretive, spending most of their time buried or tucked beneath bark.
 
This species is sensitive to drying and benefits from a stable, mature setup with moisture gradients and plenty of cover. When kept correctly, they are hardy, fascinating little detritivores that add movement and character to a forest‑floor enclosure. Their compact size, gentle nature and charming appearance make them a favourite among keepers who enjoy observing natural behaviours rather than handling.
