Bumblebee Millipede

Looks how to spot one

Exoskeleton

A hard, segmented exoskeleton made of chitin and calcium carbonate, which is shed periodically as the millipede grows. The body is long and cylindrical with many pairs of short legs.1

Personality what they are like

Bumblebee millipedes are docile, slow-moving and calm. They are not aggressive and can be handled gently, but handling should be kept to a minimum as it causes stress. When threatened they may curl up or release a mild cyanide secretion, which is harmless to humans but can irritate skin; washing hands after handling is advised.16

Daily activity how busy a day looks

Low activity needs. They are primarily nocturnal but often surface-active during the day. They enjoy climbing on branches and cork bark. No special exercise requirements beyond a well-structured enclosure.37

Grooming and care the hands-on bits

Very low grooming. The main care involves maintaining a clean, humid substrate and removing old food. Do not disturb them during moulting. Wash hands after handling due to the defensive secretion.1

Home where they are happiest

A glass or plastic terrarium with good ventilation. Minimum size 20x20x20 cm for a small group. Provide 5-8 cm of substrate made from hardwood leaf litter, rotten hardwood, and soil, never use coconut coir as it can cause impaction. Keep temperature at 22-28°C (71-82°F) and humidity at 70-80%. Mist one side of the enclosure regularly to keep the substrate damp but not waterlogged. Add branches and cork bark for climbing. Avoid direct sunlight and under-tank heating mats; heat from the side or room is safer.738

Food basics what goes in the bowl

Detritivore. Their main diet is the substrate itself, decaying hardwood leaves and rotten wood. Supplement with small slices of cucumber, sweet potato, apple, melon, or commercial invertebrate foods like Repashy Bug Burger. A constant source of calcium (crushed cuttlebone) must be mixed into the substrate.34

Company who they like around

They are gregarious and can be housed in groups without aggression. Provide plenty of hiding places and enough substrate for everyone. They are not venomous to humans, but they can release a mild cyanide secretion as a defence; this is not dangerous unless ingested. In the USA, a USDA APHIS permit is required to ship them across state lines because they are considered a potential invasive species in Florida.61

The story where it all began

The bumblebee millipede has been kept as a pet by invertebrate hobbyists for many years, prized for its bright colours and daytime activity. It was introduced to Florida accidentally via the tropical plant trade and has become naturalised there. In the pet trade it is now captive-bred and widely available, making it a popular beginner species.62
