Flatback millipedes ( Aphelidescus sp.) might not be the flashiest creatures in the Diplopoda family, but don’t let their unassuming appearance fool you. These little guys are architects of the underground world, tirelessly building elaborate burrow systems that would put any subterranean engineer to shame. With hundreds of legs propelling them through the soil, they are truly masters of movement, navigating a complex network of tunnels and chambers with impressive dexterity.
A Closer Look: Unveiling the Secrets of the Flatback Millipede
Flatback millipedes get their name from their distinctive flattened dorsal side, which gives them a unique, almost pancake-like appearance. Their bodies are segmented, with each segment sporting two pairs of legs - a characteristic shared by all millipedes. These numerous legs, though not used for speed, provide exceptional stability and traction, allowing them to navigate the challenging terrain beneath our feet with ease.
Their coloration can vary depending on the species and their environment. Some sport shades of reddish-brown or dark grey, while others exhibit striking patterns or markings. But regardless of their color scheme, flatback millipedes are masters of camouflage, blending seamlessly into the surrounding leaf litter and soil.
Lifestyle: A World Beneath Our Feet
Flatback millipedes are detritivores, meaning they feed primarily on decaying organic matter like fallen leaves, dead insects, and rotting wood. They play a crucial role in breaking down this material, recycling nutrients back into the ecosystem. As they burrow through the soil, they aerate it and create pathways for other organisms, contributing to a healthy and balanced underground environment.
These millipedes are primarily nocturnal, emerging from their burrows under the cover of darkness to search for food. They rely on their sensitive antennae to detect chemical cues in their surroundings, guiding them towards potential meals. Their mandibles, powerful chewing appendages located behind their heads, allow them to grind down tough plant material with remarkable efficiency.
While not particularly social creatures, flatback millipedes may occasionally congregate in groups, especially when food sources are abundant. They communicate with each other through chemical signals, releasing pheromones that can attract mates or warn others of danger.
Defensive Strategies: More Than Meets the Eye
Despite their unassuming appearance, flatback millipedes are equipped with several defense mechanisms to protect themselves from predators. When threatened, they will curl into a tight spiral, exposing their hard exoskeleton and protecting their vulnerable underside. Some species can also release a foul-smelling secretion from specialized glands located along their sides.
This pungent fluid is not only unpleasant to the nose but can also act as an irritant to potential attackers. While not poisonous, it effectively discourages predators from taking a bite out of these well-armed millipedes.
Reproduction: A Slow and Steady Approach
Flatback millipedes reproduce sexually, with males transferring sperm to females through a specialized structure called a gonopod. Fertilization typically occurs within the female’s body, where she will later lay her eggs in a safe and secluded location, such as a deep burrow chamber. The eggs hatch into miniature versions of their parents, equipped with all the tools they need to survive in their underground world.
The lifecycle of a flatback millipede can vary depending on environmental factors such as temperature and humidity. In favorable conditions, they may reach sexual maturity within a year or two. However, some individuals can live for several years, contributing to the ongoing cycle of decomposition and nutrient recycling in their subterranean ecosystem.

While they may not be the stars of the show, flatback millipedes are essential players in maintaining the delicate balance of life beneath our feet. Their tireless efforts in decomposing organic matter and aerating the soil contribute to a healthy ecosystem that supports a wide range of organisms. So next time you’re out for a walk in the woods, remember these tiny architects of the underground world - they may be hidden from view, but their contributions are invaluable.
