Merulanella sp. "Ember Bee"
An undescribed woodlouse from Vietnam. The legs and underside are jet black while the shell runs yellow into orange and red. It stays out and active in daylight, which makes it unusually watchable, and at about 20mm it is large for its group.
Merulanella sp. 'Ember Bee' is an undescribed woodlouse from the warm, humid forests of Vietnam; 'Ember Bee' is a breeder's line name, not a described species. The legs and underside are jet black while the shell runs yellow into orange into red, so a group crossing leaf litter looks like bees rising out of embers, which is where the name comes from. Markings differ between individuals. Adults reach about 20mm, large for the group. The genus is unsettled: since a 2025 split some sellers list it as Ardentiella while others keep the older Merulanella. The husbandry problem is holding humidity high while the air still moves, so mesh two opposing walls and let a current run through. Wet the substrate but never soak it. It does best at 20-23C and copes from 19 to 26C, but warm, wet, stagnant air empties colonies quietly. It climbs sheer surfaces, so use a tall enclosure with upright cork bark and seal every lid gap. Calcium goes fast, so keep cuttlebone in permanently.

Hardwood leaf litter and white-rotted wood as the base, with small amounts of vegetable and the occasional pinch of fish flake; permanent cuttlebone or crushed limestone
20-23C is ideal and it copes from 19 to 26C. Keep humidity in the 60s to low 70s with one end wetter than the other. Never put a heat mat under the enclosure.
It climbs, so use a tall enclosure with upright cork bark and 5-8cm of substrate. Mesh two opposing walls so air flows through, and seal every gap in the lid and seams.
Hardwood leaf litter and white-rotted wood are most of the diet. Small amounts of vegetable and the odd pinch of fish flake; clear leftovers the next day.
Harmless to people. Out and active by day as well as night, and it will roll into a ball if pushed. Kept in groups.
Warm, wet, stagnant air collapses colonies quietly. Note that sellers list it under either Ardentiella or Merulanella.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Ember Bee Isopod is 20〜23℃. Recommended humidity is 60〜73%. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Ember Bee Isopod is 2-4 years. With proper care and nutrition, they can live a long and healthy life.
Ember Bee Isopod typically reaches About 20mm as an adult. Size may vary depending on care conditions and individual genetics.
Ember Bee Isopod feeds on: Hardwood leaf litter and white-rotted wood as the base, with small amounts of vegetable and the occasional pinch of fish flake; permanent cuttlebone or crushed limestone. Aim for a balanced diet with appropriate feeding frequency.
