Chicobolus spinigerus belong to the family of Spirostreptidae and are commonly referred to as Florida Ivory Millipedes

These creatures are nocturnal scavenger feeders and are most commonly found in wet and decaying forests across parts of North America.

It gets its name from the ivory-white coloration which can often be observed on their bodies.

As the millipede moves and crawls, the segments together create an undulating snake-like movement, waves of which can be seen in the Ivory Millipede’s namesake.

These millipedes can grow up to 8.89 cm in length and about 0.25 inches or 0.5 cm in width.

They have smooth, segmented bodies with around 58 legs and two pairs of antennae that are about the same length as the body.

They also possess a pair of short, stubby antennae near the end of the body that gives off a distinct smell and taste.

With their cute little pair of eyes, they look quite charming.

Benefits Of Using Ivory Millipedes

Ivory Millipedes are ideal for use in vivariums such as paludariums and bioactive terrarium setups.

They provide a natural aesthetic for these living habitats and also fulfill an important role in the overall system.

Firstly, they aid in important aspects of soil management, breaking down decaying organic material and aerating the substrate.

This helps to reduce the chances of fungal and bacterial growth that can negatively impact the health of other inhabitants in the vivarium.

Secondly, they are an ideal source of food for other vivarium inhabitants, such as lizards, frogs, and turtles.

Lastly, they help to maintain a balanced ecosystem in the environment and facilitate the cycling of nutrients.

Ivory Millipede Facts

Chicobolus spinigerus are small, hardy terrestrial arthropods native to the southeastern United States.

These omnivorous critters prefer a diet of decaying plant matter, fresh leaf litter, and other organic materials found in the wild.

They are generally gentle and easy-going, living for many years when cared for properly, and can be bred quite easily in captivity.


The Ivory Millipede is native to the southeastern United States from Mississippi to Kentucky, as well as parts of Florida, Georgia, and Alabama.

They thrive in wet and moist habitats, such as humid forests and wetlands.

These millipedes prefer to live beneath rotting logs and in the soil, in humid and shaded areas.


In their native habitat, Chicobolus spinigerus were primarily decomposers, feeding on dead plant material.

They feed greatly on rotting leaves, plant detritus, mushrooms, and other fungi.

Due to their small size, Ivory Millipedes require frequent feedings.


The Ivory Millipede is generally a very calm species, which makes them a great pet for those wanting to observe their behavior up close.

They tend to be less active during the day, preferring to shy away when there is a lot of movement or sound.

When handled carefully, these millipedes are not typically aggressive and are not likely to bite. 

When it comes to other animals and insects, Chicobolus spinigerus is surprisingly tolerant.

They are also relatively tolerant of other millipedes, although they may show a bit of aggression if they feel threatened.


Ivory Millipedes typically live for up to 5-10 years with optimal care.

As C. spinigerus mature, they will molt several times throughout their lives.

After mating, the female will lay a clutch of up to sixty eggs, which can take several weeks to hatch.

The eggs are usually laid in soil, after which the young millipedes will become independent and have to hunt for food.

As they grow, they’ll go through several stages of molting.

Once they reach adulthood, their life span will depend on the quality of care and nutrition they receive. 


Ivory Millipedes have a unique multi-stage reproductive cycle that begins with courtship.

The male will vibrate its antennae and secrete pheromones to attract female mates.

After successful mating, the female will lay eggs in the soil of the enclosure.

The eggs will hatch in a few weeks and the newly hatched juveniles will go through several stages of growth before becoming adults.
