Trigoniulus corallinus
A small, colourful millipede with rusty-orange and dark banding — prolific breeders and an ideal starter millipede species.
About Trigoniulus corallinus
Trigoniulus corallinus is a small pantropical millipede species, now found in warm regions worldwide. They are sometimes called bumblebee millipedes for their alternating dark and orange-red banding. At just 5–7cm in length, they are much smaller than giant millipedes but make up for it with their willingness to breed readily in captivity and their attractive colouration.
Enclosure
A small, well-ventilated container is sufficient — 20×15cm for a group of 5–10. They are social and should be kept in groups. Maintain warm, humid conditions with regular misting.
Substrate
A mix of coco coir, decayed hardwood, and leaf litter, 8–10cm deep. AVOID cedar and pine substrates — these are toxic to millipedes. Keep the substrate consistently moist but not waterlogged. Add pieces of rotting wood and bark for feeding and shelter.
Feeding
Trigoniulus corallinus are detritivores and will consume:
- Leaf litter and rotting wood — their primary food source
- Vegetables and fruit as supplements
- Decaying plant matter in the substrate
Provide calcium supplementation with cuttlebone to support healthy moults and exoskeleton growth.
Breeding
One of the most prolific pet millipede species. Females lay clusters of eggs in the substrate, and hatchlings appear as tiny pale worms. Under warm, humid conditions they breed continuously. Colonies can grow rapidly — be prepared to separate or rehome offspring.
Bioactive use
Their small size makes Trigoniulus corallinus suitable for bioactive terrariums as a clean-up crew alongside isopods and springtails. They will help break down organic waste and leaf litter in larger enclosures.
