What Are Siamese pointy-tailed millipedes?

Spike Tail Millipedes, also known as Siamese Pointy-Tailed Millipedes, are small invertebrates that belong to the family of Harpagophoridae.

These distinctively large millipedes are commonly found in humid tropical and subtropical regions.

They can also be found in areas with similar climates, such as India and Southeast Asia.

The common name, Siamese Pointy-Tailed Millipede, comes from their distinctive pointy tail that is used for digging and movement.

What Do Siamese pointy-tailed millipedes Look Like?

Siamese pointy-tailed millipedes are small, dark-brown, or dark-gray arthropods that often get more vibrant as they age.

They have a long body with many segments and a pointed tail that gives them their unique name.

The body is between 9 to 11 inches long, depending on the age and sex of the millipede.

They have between 100 and 160 legs, but fewer legs on the front end near the head. 

They also have two small antennae on either side of their eyes which help them find food and navigate their environment. 

Benefits Of Using Siamese pointy-tailed millipedes

The Siamese Pointy-Tailed Millipede makes for a great addition to many types of vivariums!

Not only do they help to break up the substrate, which is beneficial for plant roots, but they also help to aerate the soil.

They also serve as a source of food for other inhabitants of the enclosure, such as birds, amphibians, reptiles, and even larger insects.

Additionally, these millipedes provide a source of entertainment for viewers since their behavior is quite interesting to watch.

Siamese Pointy-tailed Millipede Facts

The Siamese Pointy-Tailed Millipede is a small, long-bodied millipede native to Southeast Asia.

They have a natural diet of decomposing plant matter and small insects and are typically docile in temperament.

Thyropygus allevatus typically have longer lifespans than most millipedes, and while they do not typically breed in captivity, they are fairly easy to care for.


The Siamese Pointy-Tailed Millipede is native to Thailand, though it is also found in parts of Sri Lanka as well as Vietnam.

These millipedes are usually found close to the ground and in dark, wet places like mulch, forest litter, or soil.

They prefer shady habitats with lots of hiding spaces and high levels of humidity, like rotten logs and leafy humus.


In their natural habitat, Thyropygus allevatus feed primarily on decaying vegetation like fallen leaves, fruits, and flowers.

They’re also known to feed on small insects, larvae, and other sources of protein.

It’s important to note that these millipedes are not predators–rather, they’re scavengers. 

When food is not readily available in the wild, Siamese pointy-tailed millipedes have been observed to eat their shed exoskeletons.

This process provides them with important nutrients, minerals, and amino acids that would otherwise be lacking in the natural environment.


Spike Tail Millipedes are not particularly aggressive toward humans and other animals.

They tend to be shy and may curl up into a ball when stressed or threatened.

They prefer to retreat rather than fight, but they might bite if they feel they are in danger.

Otherwise, they won’t cause any harm and their bites are harmless. 

Due to their timid nature, Thyropygus allevatus do not do well in active and loud environments.

They prefer to hide and will seek out dark, quiet corners of the enclosure when they feel the need to retreat and relax.

It is essential to create a peaceful and quiet environment for the millipede to thrive. 


The average life expectancy of a Siamese pointy-tailed millipede is seven to ten years.

Thyropygus allevatus goes through a number of distinct stages of life.

The first stage is the egg stage, during which the eggs are laid on the ground. After about two weeks, the eggs hatch, and the larvae emerge.

During the larval stage, the larvae will molt, or shed their exoskeletons.

They will then undergo several more molts before reaching adulthood, during which they will reach their full size.

Once they are fully grown, the millipede will begin reproducing. 


Thyropygus allevatus typically mate and reproduce in the summer, during June and July.

The male will locate a female by following her pheromone “scent trail”, and will attempt to court her.

When mating is successful, the female lays egg capsules, which generally contain 5-25 eggs.

The young millipedes will stay with the mother for a short period, generally only a few weeks, before they disperse. 

Where To Find Siamese Pointy-tailed Millipedes

If you’re interested in finding Thyropygus allevatus in the wild, your best bet is to make a trip to Thailand.

Another way to obtain a Siamese pointy-tailed millipede is through pet stores or breeders.

Tank Requirements

Siamese Pointy-Tailed Millipedes thrive in plastic or glass enclosures with mesh lids or terrariums that are at least 10 gallons in size.

They prefer an environment with a slightly acidic pH between 6.0 and 7.8, and a hardness between 4 and 8 dKH.

A temperature of 80 to 86 degrees Fahrenheit, a substrate of peat moss, coco fiber soil, or bark, and moderate terrarium lighting must be provided.

The terrarium substrate should be kept damp, not wet, to prevent mold growth.

Be sure to provide a hiding place, such as terrarium decorations, rocks, and wood to allow them to climb and hide.

What Do Siamese Pointy-tailed Millipedes Eat?

Feeding Thyropygus allevatus can be simple and easy!

These millipedes are mostly scavengers, meaning they will typically eat anything safe for them to consume.

Here is a list of things you can feed them:

  • Leafy greens, such as kale, spinach, and lettuce
  • Fruits, such as apples, watermelons, and bananas
  • Vegetables, such as carrots, peas, and squash 
  • Small insects, such as crickets and mealworms
  • Small bits of cooked chicken, fish, or beef

You can also use special calcium and vitamin supplements designed specifically for millipedes to provide important nutrients.

When feeding your millipede, it’s important to observe them and make sure they’re eating properly and the food is not being wasted.

It’s also important to make sure the food is small enough for them to consume and isn’t too big for them.
