Thai Rainbow Millipedes (Apeuthes sp) Juvenile / Adult
NOT AVAILABLE - CARE INFO ONLY
Looking for a vibrant, shimmering centrepiece for your tropical bioactive display? The Thai Rainbow Millipede (Apeuthus sp.) is a stunning Southeast Asian species, highly sought after for its polished, multi-coloured exoskeleton and high-contrast banding.
Unlike larger, more subterranean species, Thai Rainbows are noted for their glossy finish and attractive stripes that shift in the light, making them a true visual highlight of the forest floor.
Explore the sections below for our biology-led guide on their Thai rainforest origins, their role as efficient nutrient recyclers, and why these "rainbow" detritivores thrive in our high-clarity, well-ventilated habitats.
- Southeast Asian Tropical Origins: Native to the humid, shaded forest floors of Thailand. Biologically, they are adapted to a life amongst thick leaf litter and decaying tropical hardwoods. This tropical heritage means they require consistent warmth and humidity, making them an ideal species for a dedicated tropical bioactive enclosure.
- Glossy Rainbow Morphology: These millipedes, alternatively called violet millipedes, are highly attractive with their smoky blue-grey colouration with subtle orange / red bands at each body segment, which contrast with the pinkish legs and antennae. These millipedes reach a manageable adult length of approximately 6–8cm. This glossy texture helps them navigate through damp soil and leaf litter without debris sticking to their bodies.
- Efficient Forest Floor Scavengers: As dedicated detritivores, Thai Rainbows play a vital role in their native ecosystem by breaking down fallen organic matter. They possess powerful mandibles designed for shredding decaying leaves and wood, converting waste into nutrient-rich frass that supports plant growth in a bioactive system.
- Identifying Gender: Both male and females are monomorphic, meaning they look the same, but can easily be sexed when they are a third of their adult size, by observing the underside of the seventh body segment. Females will have two pairs of legs on every body segment, but males will have small stump-like appendages called gonopods or a gap instead of a pair of legs.
- Juvenile Morphology & Behaviour: As juveniles, these are very small, white-translucent in colour, and only have 3 pairs of legs! The babies develop their colouration and other pairs of legs as they moult, and will eat some of the parents faecal pellets to improve their own gut biomes. These millipedes spend most of their time living in the substrate, consuming rotting wood and leaf litter and occasionally can be seen exploring the tank.
-
Consistent Humidity and Moisture Refuges: Coming from the humid forests of Thailand, this species is sensitive to desiccation. They require a substrate that remains damp to the touch, supplemented by a deep layer of Sphagnum moss. Our bespoke acrylic enclosures are designed to hold this moisture effectively while providing the gentle airflow necessary to prevent stagnant conditions.
- Defence Mechanisms: Like other millipedes when threatened, they will curl themselves up where the head, underside, and legs are protected by the hard exoskeleton, and can excrete a yellow toxic substance containing cyanide that can be an irritant to sensitive skin.
- Handling warning: Only handle these millipedes if they are already above ground and let them walk onto your hand, NEVER pull the millipede off a surface or search through the substrate! Disturbing a millipede whilst moulting can damage them and be potentially fatal.
